Cisco ISR4331

[hernandez.julio921]

I configure my offices cisco routers in a central location, then I ship to their destination.

The issue I am running into, is that the interface does not auto come up automatically.

I usually assign g0/0/0 for iNet, and g0/0/2 for MPLS  

even if I put the no shut command in the configuration.

Is this a bug, or a feature.

to get my interface to enable I need to console into the router and do another no shut.

I can however enable the interfaces, they'll connect and restart the router and they come up enabled.

Since my central site does not use the same ip's as the remote sites I have been sending my routers to, do I need to do something prior, maybe configuring a test router to spoof neighbor or next hop ip for iNet, then enable and then ship?

This would seem to be more work then needed, but not sure why I would need to do it this way, instead of configuring with the no shut on the interfaces.

Hello,

I had the same problem on ISR4351, with this ios : isr4300-universalk9.03.16.01a.S.155-3.S1

I updated the ios to isr4300-universalk9.03.16.05.S.155-3.S5-ext.SPA

and after it was working well.

I just checked and, I am running isr4300-universalk9.03.16.02.S.155-3.S2-ext.SPA

I will update a spare router I have here and test with your suggestion.

Hello,

the recommended fix is to add the EEM script below to your configuration, which will run at boot time and no shut the interfaces specified (you can add as many interfaces to the script as you need):

event manager applet admin-up-interface authorization bypass
event timer cron cron-entry "@reboot"
action 0.5 syslog msg "CSCux17298 WORKAROUND: Executing 'no shutdown' on all interfaces"
action 1.0 cli command "enable"
action 1.1 cli command "configure terminal"
action 1.5 cli command "interface GigabitEthernet0/0"
action 1.6 cli command "no shutdown"
action 2.0 cli command "interface GigabitEthernet0/1"
action 2.1 cli command "no shutdown"
action 2.5 cli command "interface GigabitEthernet0/2"
action 2.6 cli command "no shutdown"
action 8.9 cli command "end"
action 9.0 syslog msg "CSCux17298 WORKAROUND: Interfaces have been brought admin-up"

I have yet to try this response yet.

I may utilize this script for more redundancy.

Thanks for the submission
