I'am using router 3640
IOS : 12.0(5)1 release software (fc1)
ROM : 11.1(20)AA2
I want to apply vlan encapsulation on ether or fastether sub interface
I tried to find "encapsulation dot1q..." with "?" marker in the subinterface and it does'nt exist.
Is it possible to apply vlan on subinterface with a more recent IOS version on router 3600 ?
Thanks

Hi,
Use the Cisco Feature Navigator to find an IOS that supports dot1q for your router:
"IEEE 802.1Q VLAN Trunking"
http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp
And please be informed that the encapsulation command is only available under the subinterface not the main interface.
NOTE: Its not supported in IPBase feature set.
HTH, please do rate all helpful replies,

Hi there,
it sounds to me that most of recent routers
support this feature .and also i've checked
the Navigator.it does support.
Try to reload your router!
or if you've got another router try to replace
your IOS with another one.

Must have at leaST ip plus software to run vlans . Also that is a very old version that may not even support it . 12.0 is EOL now I believe.

After checking too I thing that I need IP plus instead of IP features set
and may be I need more RAM / flash
IOS image I thing is OK
