APAR status
Closed as program error.
Error description
If an etherchannel was configured with use_jumbo_frames=yes and the interface mtu later changed to 1500, then after every reboot the mtu is set back to 9000 in the CuAt
Local fix
Problem summary
Configured 1500 mtu is reset to 9000, on rmdev/mkdev , if use_jumbo_frames=set.
Problem conclusion
Introduced a new tunable attribute, auto_set_mtu in the adapter/ etherchannel(default:enabled). When customer wants to retain the mtu across reboots, when the use_jumbo_frames=set, he can set this to disabled, so the user configured mtu is retained.
Temporary fix
