We have cisco mwr 2941 with last software version.And we want to give IP addreses to gigabit ports. But when we do it, we see this:
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int g0/1
Router(config-if)#no sw
Command rejected: Not a convertible port.
Router(config-if)#ip add
Router(config-if)#ip add?
But in this config guide I saw that IP address can be assigned to built-in gigabit ports.
http://www.cisco.com/en/US/docs/wireless/mwr_2941_dc/software_config/guide/appB1.html
Is it hardware limitation, or software bug? We tried to use other software version, bun result was the same.
Solved! Go to Solution.

Vladimir-
The documentation for the 2941 is horribly innaccurate. You cannot assign an IP address directly to the gigabit interfaces -- you must configure an SVI and give it an addres instead. Here is an example:
interface GigabitEthernet0/0
description link to Core
switchport access vlan 100
switchport mode access
interface Vlan100
description Backhaul
ip address 10.10.5.2 255.255.255.252
no ptp enable
mpls ip
Let me know if this helps. I recently worked on a fairly large project deploying 2941's for CESoPSN pseudowire backhaul of TDM CDMA sites over IP. I may be able to help out more if you have any other questions. By the way - make sure you are using the absolute latest v15 IOS or you will have all sorts of problems.
