BTW...the vlan specified in the dot1Q must be allocated from the
interval VLAN range.  Submit the command "show vlan internal usage" to
get the next available vlan.


An example of this is

csc-core-a#sh vlan internal usage 

VLAN Usage
---- --------------------
1006 online diag vlan0   
1007 online diag vlan1   
1008 online diag vlan2   
1009 online diag vlan3   
1010 online diag vlan4   
1011 online diag vlan5   
1012 PM vlan process (trunk tagging)
1013 Control Plane Protection
1014 L3 multicast partial shortcuts for VPN 0
1015 Egress internal vlan
1016 Multicast VPN 0 QOS vlan
1017 IPv6 Multicast Egress multicast
1018 vrf_0_vlan0
1019 GigabitEthernet6/6
1020 Tunnel1
1021 Tunnel2
1022 GigabitEthernet13/23
1030 GigabitEthernet6/6.100
1031 GigabitEthernet6/6.101
1032 GigabitEthernet6/6.200

You need to specify an encapsulation for the sub-interfaces if that's
what your trying to accomplish.  Here's a working config

interface GigabitEthernet13/23
 description WAN Uplink
 no ip address
 udld port aggressive
!
interface GigabitEthernet13/23.100
 encapsulation dot1Q 1030
 ip address 10.255.0.1 255.255.255.252
!
interface GigabitEthernet13/23.101
 encapsulation dot1Q 1031
 ip address 10.255.0.5 255.255.255.252
!
interface GigabitEthernet13/23.200
 encapsulation dot1Q 1032
 ip address 10.255.0.9 255.255.255.252


I am running
s72033_rp-ADVIPSERVICESK9_WAN-M), Version 12.2(18)SXF5


Cheers,
Patrick

What is the minimum software rev for a 6500/7600 running IOS Native to
support (dot) or Subinterfaces for L3 VLAN encapsulation?

6500(config)#int g2/12
6500(config-if)#int g2/12.200
                             ^
% Invalid input detected at '^' marker.

6500(config)#encap ?
% Unrecognized command

The software rev is:

Cisco Internetwork Operating System Software IOS (tm) c6sup2_rp Software
(c6sup2_rp-PSV-M), Version 12.1(22)E6, RELEASE SOFTWARE (fc1) which I
was pretty supported it unless I am missing something obvious.

interface GigabitEthernet2/12
  ip address 192.168.0.1 255.255.255.252
  shutdown
!

Thanks in advance,

Deepak
