1.2 Interface Configuration
One-Click Configuration Deletion on an Interface
For details, see Table 1-6.
Table 1-6 One-click configuration deletion on an interface
Improvement | Involved Models | Before | Now |
One-click configuration deletion on an interface | All models | In versions earlier than V200R001, configurations on an interface need to be deleted one by one. It is time-consuming to delete the configurations if too many configurations exist. | l In V200R001 and later versions, you can run the clear configuration interface interface-type interface-num command in the system view to delete all the configurations on interfaces. l In V200R002 and later versions, you can run the clear configuration this command on an interface to delete all the configurations on the interface. |
Tips
You can run the one-click configuration deletion command to delete all the unnecessary configurations on interfaces, instead of deleting them one by one.
Example
Delete the configurations on GigabitEthernet1/0/1.
<Quidway> system-view
[Quidway] interface gigabitethernet 1/0/1
[Quidway-GigabitEthernet1/0/1] display this
#

port trunk allow-pass vlan 100
#
return
l In versions earlier than V200R001, the configuration is as follows:
[Quidway-GigabitEthernet1/0/1] undo port trunk allow-pass vlan 100
[Quidway-GigabitEthernet1/0/1] undo port link-type
l In V200R001 and later versions, the configuration is as follows:
[Quidway] clear configuration interface GigabitEthernet 1/0/1
Warning: All configurations of the interface will be cleared, and its state will be shutdown. Continue?
l In V200R002 and later versions, you can run the following command:
[Quidway-GigabitEthernet1/0/1] clear configuration this
The interface range Command Specifies the Interface Range for Batch Operations on Interfaces
For details, see Table 1-7.
Table 1-7 The interface range command specifies the interface range for batch operations on interfaces
Improvement | Involved Models | Before | Now |
The interface range command specifies the interface range for batch operations on interfaces. | All models | To perform the same operations on multiple interfaces in versions earlier than V200R003, you need to configure these interfaces one by one. | In V200R003 and later versions, you can run the interface range { interface-type interface-number1 [ to interface-type interface-number2 ] } &<1-10> command to perform the same operations on multiple consecutive or nonconsecutive interfaces. |
Tips
If you need to run the same commands on different interfaces, performing the same operations on each interface one by one is time-consuming and labor-intensive. The interface range command easily solves this problem.
Example
Configure interfaces GigabitEthernet1/0/1 to GigabitEthernet1/0/20 as trunk interfaces in a batch.
<Quidway> system-view
[Quidway] interface range GigabitEthernet 1/0/1 to GigabitEthernet 1/0/20
Configuring an IP Address for a Physical Interface
For details, see Table 1-8.
Table 1-8 Configuring an IP address for a physical interface
Improvement | Involved Models | Before | Now |
You can configure an IP address for a physical interface. | S9300, S9700, S7700, S5300HI, S5310EI, S5700HI, S5710EI, S5710HI | In versions earlier than V200R005, you need to create a VLANIF interface and then configure an IP address for the VLANIF interface. | In V200R005 and later versions, you can directly configure an IP address for a physical interface after switching the interface to Layer 3 mode, and do not need to configure a VLANIF interface for IP address assignment. |
Tips
After switching a physical interface to Layer 3 mode, you can directly configure an IP address for the interface, saving VLANIF interface and VLAN resources.
Example
Configure IP address 10.1.0.1 and subnet mask 255.255.255.0 for GigabitEthernet1/0/1.
<Quidway> system-view
[Quidway] interface GigabitEthernet 1/0/1

[Quidway-GigabitEthernet1/0/1] ip address 10.1.0.1 255.255.255.0
1.3 Stack/CSS Configuration
Three Steps Are Reduced to Two Steps for Service Port Stacking Configuration
For details, see Table 1-9.
Table 1-9 Three steps are reduced to two steps for service port stacking configuration
Improvement | Involved Models | Before | Now |
Three steps are reduced to two steps for service port stacking configuration. | S6300, S6700, S5710EI, S5310EI, S5300HI, S5700HI, S5710LI, 5700LI, S2350EI, S2750EI | In versions earlier than V200R003, the configuration procedure is as follows: 1. Enable physical stack member ports. 2. Create a logical stack port. 3. Bind the enabled physical stack member ports to the logical stack port. | In V200R003 and later versions, the configuration procedure is as follows: 1. Create a logical stack port. 2. Enable physical stack member ports and bind the ports to the logical stack port. |
Tips
Three steps are reduced to two steps for stacking configuration, simplifying stacking configuration.
Example
Configure XGigabitEthernet1/0/1 as a physical stack member port and bind it to the logical stack port 1/1.
l In versions earlier than V200R003, the configuration is as follows:
<Quidway> system-view
[Quidway] stack port interface XGigabitEthernet1/0/1 enable
[Quidway] interface stack-port 1/1
[Quidway-stack-port1/1] port member-group interface XGigabitEthernet1/0/1
l In V200R003 and later versions, the configuration is as follows:
<Quidway> system-view
[Quidway] interface stack-port 1/1
[Quidway-stack-port1/1] port interface XGigabitEthernet1/0/1 enable
A Command Is Added to Display CSS Link Status During CSS Card Clustering
For details, see Table 1-10.
Table 1-10 A command is added to display CSS link status during CSS card clustering.
Improvement | Involved Models | Before | Now |
A command is added to display CSS link status during CSS card clustering. | S9300, S7700 | In versions earlier than V200R001, no command is available to display CSS link status during CSS card clustering. When a CSS link becomes faulty, you can only view the indicator on a CSS card for analysis. | In V200R001 and later versions, the display css channel command is added to display CSS link status. |
Tips
You can run the display css channel command to view the CSS link status for CSS maintenance.

1.4 Ethernet Interface Configuration
The port link-type Command Changes the Link Type of an Interface
For details, see Table 1-11.
Table 1-11 The port link-type command changes the link type of an interface
Improvement | Involved Models | Before | Now |
The port link-type command changes the link type of an interface. | S12700, S9700, S7700, S6700, S5710HI, S5700HI, S5710EI, S5700EI, S5700SI, S5700LI, S5700S-LI, S5720HI, S5720EI, S2750EI, S2720EI, and S1720 | In earlier versions of V200R005, before changing the interface type, restore the default VLAN configuration of the interface so that the interface belongs to only VLAN 1. | In V200R005 and later versions, before changing the link type of an interface, you do not need to restore the default VLAN configuration. However, if the link type of the interface is changed, the VLAN configuration of the interface is deleted. |
Tips
You do not need to restore the default VLAN configuration of an interface before changing the link type of an interface.
Example
Change the link type of GigabitEthernet1/0/1 to access.

STP Edge Port Detection
For details, see Table 1-13.
Table 1-13 STP edge port detection
Improvement | Involved Models | Before | Now |
The switch provides STP edge port detection. | All models | In earlier versions of V200R001, an STP-enabled port is not an edge port by default, and the edge port needs to be manually specified. | In V200R001 and later versions, the edge port detection is enabled on an STP-enabled port. If the switch does not receive STP BPDUs from the remote device in a given period of time, the STP-enabled port automatically inherits attributes of the edge port (the configuration remains unchanged). |
Tips
If the switch does not receive STP BPDUs from the remote device in a given period of time, the STP-enabled port automatically inherits attributes of the edge port. This facilitates switch maintenance.
Voice VLAN Can Add the Voice VLAN ID to Untagged Packets
For details, see Table 1-14.
Table 1-14 Voice VLAN can add the voice VLAN ID to untagged packets
Improvement | Involved Models | Before | Now |
Voice VLAN can add the voice VLAN ID to untagged packets. | All models | In earlier versions of V200R003, the switch cannot add the voice VLAN ID to untagged packets. The switch must use the ACL or MAC address of a VLAN to add the voice VLAN ID to untagged packets, which is inconvenient. | In V200R003 and later versions, include-untagged is added to the voice-vlan vlan-id enable command. That is, the voice-vlan vlan-id enable [ include-untagged ] command adds the voice VLAN ID to untagged packets. |
Tips
You can use the voice-vlan vlan-id enable [ include-untagged ] command to add the voice VLAN ID to untagged packets. There is no need to use the ACL or MAC address of a VLAN. The management is convenient.
1.5 ACL
Five Steps Are Reduced to Two Steps for ACL Configuration
For details, see Table 1-15.
Table 1-15 Five steps are reduced to two steps for ACL configuration
Improvement | Involved Models | Before | Now |
Five steps are reduced to two steps for ACL configuration. | Modular switches | In versions earlier than V200R005, the configuration procedure is as follows: 1. Configure an ACL. 2. Configure a classifier and configure rules in the classifier. 3. Configure the behavior and action. 4. Configure a traffic policy, and bind it to classifier and behavior. 5. Apply the traffic policy. | In V200R005 and later versions, the configuration procedure is as follows: 1. Configure an ACL. 2. Apply the ACL. |
Tips
The number of steps for ACL configuration is reduced from 5 to 2. You only need two steps to complete ACL configuration, improving work efficiency.
Example
Configure ACL on GE1/0/1 to filter packets. Only the packets with source address 192.168.0.2/32 are allowed to pass.
l In versions earlier than V200R005, the configuration procedure is as follows:
<Quidway> system-view
[Quidway] acl 3000
[Quidway-acl-adv-3000] rule permit ip source 192.168.0.2 0
[Quidway-acl-adv-3000] quit

ACL-based Simplified Traffic Policy Allows You to Apply ACL Globally, to a VLAN, or to an Interface Without Creating It and Supports Dynamic ACL Update
For details, see Table 1-16.
Table 1-16 ACL-based simplified traffic policy allows you to apply ACL globally, to a VLAN, or to an interface without creating it and supports dynamic ACL update
Improvement | Involved Models | Before | Now |
With an ACL-based simplified traffic policy, you can apply ACL globally, to a VLAN, or to an interface without creating it and dynamic ACL update is supported. | Fixed switches | In versions earlier than V200R005, the configuration procedure is as follows: 1. Create an ACL. 2. Bind the ACL to a simplified traffic policy. 3. To modify an ACL rule, cancel the application of the rule in the specified view. | In V200R005 and later versions, the configuration procedure is as follows: 1. Configure a simplified traffic policy. 2. Create an ACL or modify the ACL rule. |
Tips
In V200R005 and later versions, you can bind a traffic policy to an ACL without creating the traffic policy first and modify the ACL rules.
Example
Configure ACL-based packet filtering globally.
In versions earlier than V200R005, the configuration procedure is as follows:
[Quidway] traffic-filter inbound acl 3010
Error: The ACL 3010 does not exist. (The ACL must be created first.)

A Mini USB port is added to a switch so that you can log in to the switch from a laptop or other portable devices without serial ports. | S5300LI, S5310EI, S5320EI, S5700LI, S5700S-LI, S5710EI, S5720EI, S5710HI, S5720HI | Previously, you must use the console port of these product models for the first login. Therefore, the operation terminal must have a serial port for login. In real-world applications, field engineers usually use laptops without serial ports, which cannot be used for switch maintenance. | New models available in V200R001 and later versions have a Mini USB port. You can connect a laptop to this port to log in to and manage a switch. |
Tips
If you use a laptop as an operation terminal, connect it to the Mini USB port of a switch to log in to and maintain the switch.
The following figure shows the Mini USB port on a switch.
Multiple Mode Indicators Are Added to the Front Panel to Help Determine the Running State of a Switch More Conveniently
For details, see Table 1-19.
Table 1-19 Multiple mode indicators are added to the front panel to help determine the running state of a switch more conveniently
Improvement | Involved Models | Before | Now |
Multiple mode indicators are added to the front panel to help determine the running state of a switch more conveniently. | S2350, S5300LI, S5310EI, S5320EI, S2750, S2720, S5700LI, S5700S-LI, S5710EI, S5720EI, S5710HI, S5720HI | The old models have only one mode indicator, and users have to check the running status of a switch using commands. | New models available in V200R001 and later versions have new mode indicators RPS, STAT, SPED, and STCK, through which field engineers can determine device running status directly. |
Tips
Mode indicators on the new models include RPS, STAT, SPED, STCK, and PoE, and you can observe these indicators on a switch to determine the running status of the switch.

GE/10GE and Uplink/Downlink Ports Are Identified More Clearly
For details, see Table 1-20.
Table 1-20 GE/10GE and uplink/downlink ports are identified more clearly
Improvement | Involved Models | Before | Now |
GE/10GE and uplink/downlink ports are identified more clearly. | S2350, S5300LI, S5310EI, S5320EI, S2750, S2720, S5700LI, S5700S-LI, S5710EI, S5720EI, S5710HI, S5720HI | On the old models, uplink and downlink ports on the front panel do not have distinctive identifiers, so it is not easy for users to identify the type and usage of the ports. | New models available in V200R001 and later versions identify uplink and downlink ports with different colors, making it easy to determine the type and usage of ports. |
Tips
New models available in V200R001 and later versions identify uplink and downlink ports with different colors (for example, yellow for uplink ports) and mark the port speeds above the ports. You can easily identify uplink/downlink ports and port speeds.
No distinctive identifiers for ports on an old model:

LINK/ALM Indicators of Ports on an EH1D2VS08000 CSS Card Indicate Whether Cluster Cables Are Correctly Connected
For details, see Table 1-21.
Table 1-21 LINK/ALM indicators of ports on an EH1D2VS08000 CSS card indicate whether cluster cables are correctly connected
Improvement | Involved Models | Before | Now |
If the LINK/ALM indicator of a port on an EH1D2VS08000 CSS card is steady red, the cluster cable on this port is not connected in compliance with the connection rules. Only the EH1D2VS08000 CSS card supports this function. | S9706, S9712, S12708, S12712 | To check whether cluster cables are connected correctly, you need to start the switches. Once incorrect cluster cable connections are found, you need to reconnect cluster cables onsite. | You can determine whether cluster cables are connected correctly by observing LINK/ALM indicators on CSS cards, and make sure all cluster connections are correct before logging in to the switch. This improves the cluster setup efficiency. |
Tips
On the new models, you can determine whether cluster cables are connected correctly by checking LINK/ALM indicators of ports on CSS cards. Only the EH1D2VS08000 CSS card supports this function. The following figure shows indicators on this card.
