3750 Metro series do not dot1q trunking??

[NAVIN PARWAL]

Folks,

I have a 3750 metro series switch and i am trying to use it to do inter vlan routing. I do not see an option for "encapsulation dot1q" under sub interface?? why is it not supported??

Thanks

Navin,

The 3750 Metro series switch does not support Layer 3 trunks; you cannot configure subinterfaces or use the encapsulation keyword on Layer 3 interfaces. The switch does support Layer 2 trunks and Layer 3 VLAN interfaces, which provide equivalent capabilities.

For more information, see the note under Table 12-5 on this page: http://www.cisco.com/en/US/products/hw/switches/ps5532/products_configuration_guide_chapter09186a00803960dc.html#wp1326724.

Cheers,

Josef.
