How to reduce the number of LSPs on S series switches

2

After MPLS LDP is enabled, LSPs are automatically established. If no policy for controlling LSP establishment is configured, a large number of LSPs are established, wasting resources.
To reduce the number of LSPs, you can run the lsp-trigger { all | host | ip-prefix ip-prefix-name | none } command in the MPLS view to set a policy for LSP establishment.
If the all parameter is specified, all static and IGP routes trigger LSP establishment (not recommended). If the host parameter is specified, host IP routes with 32-bit addresses (excluding host IP routes with 32-bit interface addresses) trigger LSP establishment. If the ip-prefix parameter is specified, the IP prefix list triggers LSP establishment. If the none parameter is specified, LSP establishment is not triggered.
The lsp-trigger command configures policies only for ingress and egress LSPs on the public network and ingress and egress LSPs on the private network that are established using IGP routes. To configure a policy for triggering the transit LSP establishment, run the propagate mapping command.
If the lsp-trigger command is run on the ingress node, the ingress node uses all 32-bit routes to establish LDP LSPs. If the lsp-trigger command is run on the egress node, the egress node uses local 32-bit routes to establish LDP LSPs.

How to configure static LSPs on S series switches
For static LSP configuration on S series switches (except the S1700), see "CLI-based Configuration > Configuration Guide - MPLS > Static LSP Configuration > Configuration Examples > Example for Configuring Static LSPs" in S7700&S9700 V200R010C00 Product Documentation. Configurations on different models are the same, and configurations on the S7700 and S9700 are used as examples.

Can I view the port number on an S series switches
No command is available to display the port number of a data packet on an S series switches. To obtain the port number of a data packet, run the display mac-address command to view the source MAC address of the packet, determine the port receiving the packet, and then use Wireshark to capture it.

How to view the serial number of an S series switch
Serial numbers of S series switches fall into two categories: - Equipment serial number (ESN): indicates the serial number of a switch. The ESN of a modular switch is also called the chassis serial number. - Serial number (SN) of each component: indicates the serial number of a card, subcard, optical module, power supply, or fan module. Select one of the following methods to obtain the ESN or SN of a switch or component: Method 1: View SN labels. Equipment or chassis SN: View the SN label attached to the device panel. (There is a slight difference between label locations on different models. For example, the label can locate on the front, rear, or top of the chassis.) Card serial number: View the SN label on the panel (upper-right or upper-left corner) or PCB (remove and check the card). Method 2: Run a command. Run the display elabel command to view the electronic label of each component. The BarCode field indicates the serial number. Method 3: Through the web system. When the web system is enabled on a device, view the chassis serial number through the web system. EasyOperation web system (supported only in V200R005 and later versions) Log in to a device through the web system and click Monitor on the toolbar to enter the Monitor page. You can view device information, including the chassis serial number. Web system classical version Log in to a device through the web system and click Device Summary on the toolbar to view device information, including the chassis serial number.

Interface numbering of cards on S series switches
The numbering rules for interfaces are as follows. Before the clustering function is enabled, interfaces on the switch are numbered in the format of slot ID/subcard ID/interface sequence number. After the clustering function is enabled, interfaces on the switch are numbered in the format of chassis ID/slot ID/subcard ID/interface sequence number. - Chassis ID: indicates the ID of a member switch in the CSS system, with the value of 1 or 2. - Slot ID: indicates the slot where a card is installed. - Subcard ID: indicates the ID of a subcard on the LPU. - Interface sequence number: indicates the number of each interface on the card. For example, if a card is installed in slot 3 of a switch, the fifth interface from left to right and top to bottom on the card is numbered 3/0/4. If the clustering function is enabled and the cluster ID is 1, the interface is numbered 1/3/0/4. Particularly, a 40GE interface can be split into four 10GE interfaces. Then, the numbering rules for interfaces are as follows: If the 40GE interface is numbered 40GE x/y/0/n, the four converted 10GE interfaces are numbered 10GE x/y/1/(4n+z). - x: indicates the chassis ID, that is, the cluster ID. The value exists only in a cluster. - y: indicates the slot number of a card. - n: indicates the sequence number of a 40GE interface, starting from 0. - z: indicates the interface location. The value is in the range from 0 to 3. For example, before the clustering function is enabled, a 40GE interface is numbered 40GE1/0/1. The four 10GE interfaces are numbered 10GE1/1/4, 10GE1/1/5, 10GE1/1/6, and 10GE1/1/7.
