How to check whether the IP address in neighbor information is correct on S series switches

4

On Huawei S series switches (except the S1700), run the lldp management-address command to configure the LLDP management IP address. Check whether the IP address on neighbor devices is the same as that configured using this command.

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.

Whether the DHCP function of S series switch support static IP address check
After DHCP snooping is configured, S series switches do not check static IP addresses by default. You can enable the IPSG function and configure static binding entries to enable the static IP address check function.

Method to check IP addresses allocation on S series switches
For S series switches excluding the S1700, run the following commands as required to check IP addresses allocation: - If IP addresses are assigned based on the interface address pool, run the display ip pool [ interface interface-pool-name [ start-ip-address [ end-ip-address ] | all | conflict | expired | used ] ] command. - If IP addresses are assigned based on the global address pool, run the display ip pool [ name ip-pool-name [ start-ip-address [ end-ip-address ] | all | conflict | expired | used ] ] command. Note: - Specify all to check allocation of all the IP addresses. - Specify conflict to check conflicting IP addresses. - Specify expired to check expired IP addresses that are in idle state. - Specify used to check used IP addresses. - Specify start-ip-address [ end-ip-address ] to check allocation of an IP address or some IP addresses.

Check DHCP information on S series switches
Method to check DHCP information on S series switches: - Run the display ip pool [ name ip-pool-name [ start-ip-address [ end-ip-address ] | all | conflict | expired | used ] ] command to check address allocation in interface address pool mode. - Run the display ip pool [ name ip-pool-name [ start-ip-address [ end-ip-address ] | all | conflict | expired | used ] ] command to check address allocation in global address pool mode. - Run the display dhcp server database command to check the names and directories of files in which DHCP data is saved. - Run the display nat-policy template [ template-name ] command to check the configuration of the DHCP Option template. - Run the display dhcp relay { all | interface interface-type interface-number } command to check DHCP server or DHCP server group information on the interface configured with the DHCP relay function. - Run the display dhcp server group [ group-name ] command to check the configuration of the DHCP server group. - Run the display dhcp client command to check information about DHCP clients. - Run the display dhcp server statistics command to check statistics on received and sent DHCP packet by the switch used as the DHCP server. - Run the display dhcp relay statistics command to check statistics on received and sent DHCP packet by the switch used as the DHCP relay agent. - Run the display dhcp client statistics [ interface interface-type interface-number ] command to check statistics on received and sent DHCP packet by the switch used as the DHCP client. - Run the display dhcp statistics command to check statistics on received and sent DHCP packet by the switch.

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.
