NOS - set MTU on all interfaces in VLAN / on all interfacese - how to?

[Pawel_Eljasz]

hi everybody,

I'm on nos 7.3.0aa and I'd like to ask is it possible to set MTU on all or a group(like in a vlan)?
I've tried :

sw0(config)# ip mtu ?

but it does not seem to have an effect(at least not immediate)
Many thanks.

Hi Pawel,

How do you verify it did not take effect? From what I see (on a slightly different NOS7 version) it changes in show command output, but not reflected in config for every single interface:

code:

VCS-COK-SRV-Spine1# sh ip int ve 421
 Ve 421 is up protocol is up
 Primary Internet Address is 172.16.190.221/27 broadcast is 172.16.190.223
 IP MTU is 1500
...
VCS-COK-SRV-Spine1# sh ip int ve 422
 Ve 422 is up protocol is up
 Primary Internet Address is 172.16.190.253/27 broadcast is 172.16.190.255
 IP MTU is 1500
...
VCS-COK-SRV-Spine1(config)# ip mtu 2000
VCS-COK-SRV-Spine1(config)# 
VCS-COK-SRV-Spine1(config)# do sh ip int ve 421
 Ve 421 is up protocol is up
 Primary Internet Address is 172.16.190.221/27 broadcast is 172.16.190.223
 IP MTU is 2000
...
VCS-COK-SRV-Spine1(config)# do sh ip int ve 422
 Ve 422 is up protocol is up
 Primary Internet Address is 172.16.190.253/27 broadcast is 172.16.190.255
 IP MTU is 2000
...

Many thanks,
