Brocade ICX 7450 one LAG interface up and down issue

pradeep_sonawne — Fri, 22 Feb 2019 04:25:00 GMT

Hi experts,

we have brocade ICX 7450 switches, using for Core and distribution, core and distribution are connected to each other by LAG.
one of the distribution's LAG interface port getting up and down continuously. i have checked there no any cable issue, no CRC errors on both interface , even i enabled optic monitoring on distribution's interface eth1/2/1 to check if there any optic issue, but that also ok.

i unable fix the issue, need your help to fix the issue

Configuration as below
-------------------------------------------------------------
Core Switch

lag 4WH dynamic id 4
ports ethe 1/3/4 ethe 2/3/4
port-name "##Connected to 4WH DIST eth 1/2/2##" ethernet 1/3/4
port-name ###Downlink_To_DIST### ethernet 2/3/4
-------------------------------------------------------------
Distribution switch

lag 4WH dynamic id 1
ports ethe 1/2/1 to 1/2/2
port-name ###Uplink_to_Access_SW### ethernet 1/2/1
port-name ##Connected_to_5.1_CoreSwitch_onPort_1/3/4### ethernet 1/2/2
--------------------------------------------------------------

I do not see why it just started. I would try different optics or different cables, a restart, or a firmware change.

In our environment, I have maybe 15 LAGs coming off of two stacked 7450-48F units to various 7150-48P stacks at the edge.

Thus far everything has been rock solid.

Hi Pradeep,

Sorry for the problem you are having.

Do you have syslog servers and if you see anything in the log before the port started to bounce?

Please provide me the history:
When did the issue occur?
was it working fine before?
Was any changes made recently to the config?
Was the code upgraded?

Please get outputs from both side for the bouncing ports in question:
skip
show lag id
show int e 1/2/1 (1/3/4 on the other switch)
show interface int e 1/2/1 | i line | utilization (3 times)
show stat e 1/2/1 (2 times 30 seconds apart)
show sysmon count all
show optic 1/2/1
show media e 1/2/1
dm statistics
show lag brief
show log
page
Hope this helps.
Regards
Hashim

Hi Sir,

i catch below interface output, as i observed when eth1/2/1 start bouncing the core switch port show LACP BLOCKED

here is the output
