Please log in for more thread options on routers. I have a 2611 router which is connected via a 10Meg ethernet connection to my 2650 switch (which in turn is connected to another 2650 switch). Unfortunately when I try to configure sub interfaces as per the text in my book I'm receiving this error message: '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.' I've tried many different combinations of commands on the interface & subinterfaces but the CLI doesn't even recognise the 'encapsulation' command, I'm thinking that something needs to be configured globally but I'm not sure, certainly my book hasn't indicated that. I've searched the Cisco web site & also my CCNA Command quick reference guide but with no joy in solving the problem, can anyone point out where I'm going wrong? TIA, Jase. | ||||||||||||||||||||||||||||

There's only a few IOS images that support 802.1Q encapsulation on your 2611 router. Search in the feature navigator for 'IEEE 802.Q VLAN Trunking' feature for your router. Part of knowing cisco is knowing their website for finding information. Find the feature navigator and find the images that support that feature.. :) Most likely, you'll have to upgrade to one of the images returned to support what you want to do. | ||||||||||||||||||||||||||||

IIRC dot1q is only supported in IP Plus or better on that platform. -- Please excuse my bad English/German/French/Greek/Cantonese/Klingon/... | ||||||||||||||||||||||||||||

You'll have to upgrade, and consult the Feature Navigator like I previously posted to find which images do support that feature. | ||||||||||||||||||||||||||||
