Router 1921 Requirements for EHWIC-4ESG

Hi Guys,

 

I want to install a module EHWIC-4ESG into a 1921 Router.

When I try to enable the service module, it says I've not enough memory ("Memory size does not meet the requirements of Embedded-Service-Engine0/0").

My router has 512MB of memory, but I can't find the memory sizer required to enable the service module ?

Can anyone point me to correct documentation ?

Thanks & Best Regards,

Jean-Christophe

Hello,

 

512 is the maximum your router supports, the EHWIC-4ESG requires 256MB, so you should be fine.

 

Can you post the output of 'show ip int brief'...

Hi,

Below is the show ip int brief:

fab.wifi#sh ip int brie
Interface                  IP-Address      OK? Method Status                Protocol

 Also below is the configuration of the Embedded-Service-Engine and Gi0/0 interface:

fab.wifi#sh run int E0/0
Building configuration...

Current configuration : 176 bytes
!
interface Embedded-Service-Engine0/0
 ip unnumbered GigabitEthernet0/0
 service-module ip address 10.10.10.9 255.255.255.0
 service-module ip default-gateway 10.10.10.1
end

fab.wifi#sh run int Gi0/0
Building configuration...

Current configuration : 200 bytes

interface GigabitEthernet0/0

 ip virtual-reassembly in

end

Thanks a lot for your support.

Hi Jean

512 should be enough

Q. Are there any additional memory requirements for the Cisco EtherSwitch EHWICs?

A. No, the Cisco ISR G2 platforms come with a minimum of 256 MB, which is more than enough to accommodate one or more EHWICs.
Try escalating it to the TAC.
