I have a 2610 router and I am attempting to enable DOT1Q on eth0/0.1 for router-on-a-stick configuration.
My sh ver is as follows:
Cisco Internetwork Operating System Software
IOS (tm) C2600 Software (C2600-I-M), Version 12.2(8)T5, RELEASE SOFTWARE (fc1)

Image text-base: 0x80008074, data-base: 0x80A2BD40
ROM: System Bootstrap, Version 11.3(2)XA4, RELEASE SOFTWARE (fc1)
Router uptime is 39 minutes
System returned to ROM by reload
System image file is "flash:c2600-i-mz.122-8.T5.bin"
cisco 2610 (MPC860) processor (revision 0x203) with 28672K/4096K bytes of memory.
Processor board ID JAD042108TF (1440777694)
M860 processor: part number 0, mask 49
X.25 software, Version 3.0.0.
1 Ethernet/IEEE 802.3 interface(s)
32K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read/Write)
Configuration register is 0x2102
Now the problem is I can not enter the encapsulation command as you can see here:
Enter configuration commands, one per line. End with CNTL/Z.
% Invalid input detected at '^' marker.
Any reason for this? I thought IOS 12.2 should have dot1q capability.
