The method of S series switches to modify interface IP

11

S series switches (except S1700) delete or modify the interface IP address as follows:
- To delete an IP address of an interface, you can execute the command in interface-view:undo ip address[ip-address{mask|mask-length}]�?e.g.�?[HUAWEI] interface Vlanif 100
[HUAWEI-Vlanif100] display this
#
interface Vlanif100
ip address 10.1.1.1 255.255.255.0
#
[HUAWEI-Vlanif100] undo ip address
[HUAWEI-Vlanif100] display this
#
interface Vlanif100
#
- To modify an IP address or mask of an interface, you can execute the command again in interface-view:ip address[ip-address{mask|mask-length}]�?e.g.�?[HUAWEI] interface Vlanif 100
[HUAWEI-Vlanif100] display this
#
interface Vlanif100
ip address 10.1.1.1 255.255.255.0
#
[HUAWEI-Vlanif100] ip address 10.2.1.1 255.255.0.0
[HUAWEI-Vlanif100] display this
#
interface Vlanif100
ip address 10.2.1.1 255.255.0.0

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.
