Cisco-C2960交换机
奇怪的现象:有许多地方像是华为的模式。

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

------------------------------------------------------------------------------ Primary Secondary Type Ports ------- --------- ----------------- ------------------------------------------ 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。
