Display IPv6 neighbor entries on S series switches

8

On S series switches (except S1700 switches):
Run the display ipv6 neighbors command to display neighbor entries.
Dynamic and static neighbor entries are displayed in the command output. By checking the information, you can:
Determine whether the local device has learned the MAC address of the neighbor.
Check the neighbor status of the local device (for example, neighbor is unreachable, neighbor is reachable, neighbor reachability is unknown).
You can run one of the following commands as required:
�?To view the neighbor entry based on the IPv6 address of the neighbor, run the display ipv6 neighbors [ ipv6-address ] command.
�?To view the neighbor entry based on the interface number of the neighbor, run the display ipv6 neighbors interface-type interface-number command.
To view the neighbor entry on a VLANIF interface, run the display ipv6 neighbors [ vid vlan-id ] interface-type interface-number or display ipv6 neighbors interface-type interface-number [ vid vid ] command.
�?To view the neighbor entry on a QinQ termination sub-interface or dot1q termination sub-interface, run the display ipv6 neighbors interface-type interface-number vid vid [ cevid cevid ] command.
If you do not specify any parameter when running the display ipv6 neighbors command, all neighbor entries are displayed.

Aged ARP entry display on S series switches
On S series switches (except S1700 switches), aged ARP entries cannot be displayed. You can only view the current ARP table.

Configure OSPF neighbor authentication on an S series switch
OSPF authentication of S series switches includes area authentication and interface authentication. 1. Area authentication Run the authentication-mode command in an OSPF area view to set the authentication mode and password for the OSPF area. For example: [HUAWEI] ospf 100 [HUAWEI-ospf-100] area 0 [HUAWEI-ospf-100-area-0.0.0.0] authentication-mode simple cipher huawei To configure MD5 authentication, run the following command: [HUAWEI-ospf-100-area-0.0.0.0] authentication-mode md5 1 cipher huawei 2. Interface authentication The interface authentication mode is used among neighbor switches to set the authentication mode and password. Its priority is higher than that of the area authentication mode. Run the ospf authentication-mode command in the interface view to set the authentication mode and password for adjacent switches. For example: [HUAWEI] interface vlanif 100 [HUAWEI-Vlanif100] ospf authentication-mode simple cipher huawei To configure MD5 authentication, run the following command: [HUAWEI-Vlanif100]ospf authentication-mode md5 1 cipher huawei Note: When configuring area authentication or interface authentication, all switches involved must have the same authentication mode and password. If not, the switches may fail to set up an OSPF neighbor relationship.

Check OSPF neighbor information on S series switches
You can run the display ospf peer command on an S series switch with OSPF configured to check whether the OSPF neighbor status is normal. For example: [HUAWEI] display ospf peer OSPF Process 1 with Router ID 10.1.1.2 Neighbors Area 0.0.0.0 interface 10.1.1.2(Vlanif100)'s neighbors Router ID: 10.1.1.1 Address: 10.1.1.1 GR State: Normal GR State: Normal State: Full Mode:Nbr is Slave Priority: 1 DR: 10.1.1.2 BDR: 10.1.1.1 MTU: 0 Dead timer due in 35 sec Retrans timer interval: 5 Neighbor is up for 00:00:05 Authentication Sequence: [ 0 ] Note: If Full is displayed in State, LSDB synchronization has been completed and the two switches have set up the full adjacency relationship.

Check binding tables for IPSG on S series switches
You can check binding tables for IPSG on S series switches (except S1700 switches) as follows: 1. Run the display dhcp static user-bind all command to check static binding entries. 2. Run the display dhcp snooping user-bind all command to check dynamic DHCP snooping binding entries.
