7600/6500 L3 sub-interface Limited
November 24th, 2008 No Comments »
环境：
76做汇聚层交换机。
问题：
客户在2口上开启3层功能，应用单臂路由来提供vlan间的路由。当配置到封装类型时报错：
C7609-2(config-subif)#interface GigabitEthernet1/1.1
C7609-2(config-subif)# encapsulation dot1Q 11
Command rejected: VLAN 11 cannot be allocated. VLANs 1-1005 are VTP VLANs
VTP mode is client or server and must be changed to Transparent to use VLANs 1-1005
C7609-2(config-subif)# ip address 10.171.0.93 255.255.255.252
% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.
解决问题：
在交换机上，在2层端口上启用3层功能是受限制的，根据版本及硬件不同，限制也有所差别。现在拿65和76举例。
