Hello,
We have a 2921 with a EHWIC-D-8ESG-P module for service to a local telecom closet. The building is being serviced by two switches connected to a gig port with subinterfaces. Is there a way to use the subinterfaces defined on the gig port on the EHWIC-D-8ESG-P module?
R1#sh ip int bri
Interface IP-Address OK? Method Status Protocol
Embedded-Service-Engine0/0 unassigned YES NVRAM administratively down down
GigabitEthernet0/0 172.16.1.190 YES NVRAM up up
GigabitEthernet0/1 unassigned YES NVRAM up up
GigabitEthernet0/1.101 10.100.49.1 YES NVRAM up up
GigabitEthernet0/1.201 10.200.49.1 YES manual up up
GigabitEthernet0/1.501 172.22.4.1 YES NVRAM up up
GigabitEthernet0/1.551 172.26.4.1 YES NVRAM up up
Solved! Go to Solution.

Hi dpita,
I don't think you can create subinterfaces on the EHWIC-D-8ESG-P as the ports are layer 2 but an alternative is to create SVIs for each subinterface or subnet and then trunk it to the switch via one or bundle of ports from the EHWIC module.
Hope this helps.

Thanks!
I ended up removing the EHWIC since we needed a fiber link and no one wanted to buy a media converter to use the EHWIC.
