question on router on a stick

the_return_of_the_Ring

i'm trying to do a router on a stick in my lab. But i didn't see "encapsulation" command on the interface of my fastethernet at all. I'm using 2620, and the ios is 12.2. can someone tell me why this happened?

you will need to use a sub-interface

config# int fa0/0.1
config-int#encapsulation dot1q (vlan number)


if not available still check code version

i did. here's what's giving me

2620#conf t
Enter configuration commands, one per line. End with CNTL/Z.
2620(config)#int fa0/0.1
2620(config-subif)#en?
% Unrecognized command
2620(config-subif)#ip address 172.18.2.1 255.255.255.0

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 IS
L vLAN.

2620(config-subif)#

you need to get some more flash you will need 16mb


try to get 12.2(29) enterprise version or something in that version line..
if you get 12.3 best of luck finding a version that has it other than 12.3(15) IP/IDS/FW/IPSec which does require 32/16

the_return_of_the_Ring

are you sure 32mb/8f can not support the "encap" command? I thought i should be an issue of ios version. and i believe v12.2 should support it. what's wrong.

keenon

which revision and version of 12.2? there are several versions:

ip
ip plus
enterprise
enterprise plus

ect.

then you have to look at revision numbers for each version

A quick check of
http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp
for 2620 support for "IEEE 802.1Q VLAN Trunking" in the 12.2 version seems to indicate that you need at least an IP Plus or Enterprise Basic version to support Trunking.

Thanks for that link. Looking further, based on the image filename, you have IP which doesn't support VLAN.
c2600-i-mz.12.2-7c.bin as opposed to
c2600-is-mz.12.2-7c.bin
