Unable to change PortChannel mtu size #18695

Open mbze430 opened 6 months ago

mbze430 commented 6 months ago

Description

after creating a portchannel interface changing the portchannel mtu I get a message that the portchannel doesn't exist

Steps to reproduce the issue:

  1. sudo config portchannel add PortChannel02
  2. sudo config interfaces mtu Ethernet80 9216
  3. sudo config interfaces mtu Ethernet84 9216
  4. sudo config interface mtu PortChannel02 9216
  5. show interface portchannel 
    Flags: A - active, I - inactive, Up - up, Dw - Down, N/A - not available,
   S - selected, D - deselected, * - not synced
No.  Team Dev       Protocol     Ports
-----  -------------  -----------  -----------------------------
01  PortChannel01  LACP(A)(Up)  Ethernet104(S) Ethernet108(S)
02  PortChannel02  LACP(A)(Dw)
  6. show interfaces status Ethernet80-84 
    Interface    Lanes    Speed    MTU    FEC    Alias    Vlan    Oper    Admin    Type    Asym PFC

Describe the results you received:

Invalid port PortChannel02

Describe the results you expected:

The portchannel mtu to be changed to 9216

MTU (as several other port properties) can't be configure on PortChannel, the way to achieve functionality is to configure ports. When adding to PortChannel, SW will verify that all ports have same MTU

mbze430 commented 6 months ago

if I set the Ethernet80 and 84 to 9216 and add them to PortChannel02 it will say the MTU size is mismatched, and won't add it. Hence, why I try to change the portchannel mtu size BEFORE adding the interface.

@mbze430 Please see if https://github.com/sonic-net/sonic-utilities/pull/3300 works for you
