how do i configure subinterfaces in NME-16ES-1G module, as i need to have dot1q encapsulation configured on the subinterfaces.
I am not able to configure subinterfaces on the fastethernet interface.
Kindly let me know how can i do it.
Thanks

You have to configure the port as an L3 routed port before you can use sub-interfaces. use:
sw(config)#int port-num
sw(config-sw)#no switchport

Port is configured as L3 and still i am not able to use sub-interfaces
interface FastEthernet1/0/14
no switchport
no ip address
speed 100
duplex full
end
i need do the following config:
nterface FastEthernet0/1.1
encapsulation dot1Q 9
ip address 220.134.110.14 255.255.255.252
no cdp enable
!
interface FastEthernet0/1.2
encapsulation dot1Q 51
ip address 220.134.110.18 255.255.255.252
no cdp enable
!
interface FastEthernet0/1.3
encapsulation dot1Q 52
ip address 220.134.110.22 255.255.255.252

Nagesh,
You cannot configure sub-interfaces on the etherswitch module. Its not supported. I have tested this in the lab and like I suspected you are not able to create sub interfaces on the ports. You can either make them a "switchport" (layer 2) and then use the vlan interface and then associate that port with that vlan. Or to do the "no switchport" (layer 3) interface that you can assign an ip address to it. I get the invalid marker when I tried to do the int fa1/0/15.1 as an example
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#int fa1/0/15
Switch(config-if)#
Switch(config-if)#
Switch(config-if)#
Switch(config-if)#exit
Switch(config)#int fa1/0/15.1
^
% Invalid input detected at '^' marker.
Switch(config)#
HTH,Please rate if it does.
