     Cisco-C2960交换机  

    奇怪的现象:有许多地方像是华为的模式。

    奇怪的VLAN配置模式:

    从下面可以看出,此交换机支持最多4094个vlan。vlan的配置模式也跟思科的不一样。

  创建vlan 4089并在此vlan设置管理ip。

Cisco-C2960#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Cisco-C2960(config)#vlan ?
  WORD      ISL VLAN IDs 1-4094
  internal  internal VLAN

Cisco-C2960(config)#vlan 4089
Cisco-C2960(config-vlan)#exit 
% Failed to create VLANs 4089
Extended VLAN(s) not allowed in current VTP mode.
%Failed to commit extended VLAN(s) changes.

Cisco-C2960(config)#int vlan 4089
Cisco-C2960(config-if)#ip add 192.168.1.5 255.255.255.0

Cisco-C2960(config)#exit
   

    奇怪的VLAN信息:

    查看VLAN信息,居然没有4089VLAN的信息,明明刚才我们是可以创建并在4089VLAN上配置了管理ip 。

Cisco-C2960#show vlan

    最后配置网关:

Cisco-C2960(config)#ip default-gateway 192.168.1.1 

    结果这个vlan的管理ip是无法访问的。那么怎么办呢?

  问题所在就是4089这个vlan虽然我们创建了,有可能这个交换机根本就不支持4094多个vlan;但查看vlan信息却没有查到此vlan的信息。于是删除配置在vlan 4089上的ip和删除vlan 4089,后重新创建小于1005的vlan配置管理ip就行了。
