C9300-48U : when I issue the command 'sh auth sess' it takes over a minute to produce output :

I'm also seeing this throughout the log

Feb 9 10:29:44.695 AEDT: %FMFP-3-OBJ_DWNLD_TO_DP_FAILED: Switch 1 R0/0: fman_fp_image: WRClient 0x165c44f3 download to DP failed

We decided to upgrade to latest version Everest-16.6.2  ED and but same logs still coming and still slow in running the same command.

doing this command also takes a long time

xxxx#sh auth brief switch active r0


but doing either of these commands :


xxxx#sh auth sess int g1/0/1
xxxx#sh auth sess int g1/0/1 detail

is instant. Only issue with running show authentication session & sh auth brief switch active r0

Does any one have faced same issue and found resolution ?

 

Config of one of the interface is as below.

Run through few debug but nothing came out.

Cisco recently released new version Everest-16.6.3  ED (02-Mar-2018). After upgrading to that version issue got fixed. One minute reduced to 2 second to produce output.

Check CPU usage and mainly dot1x process?

We tested by doing no ip domain-lookup but no luck. Also CPU was normal. Except that command everything works fine.

 

We also taken few mab and aaa related debug but nothing showing clue.

Lookup for bugs related to your IOS. Also, check mem usage and how much mem
allocated for that process.

Memory and CPU normal. We initially suspected IOS issue hence upgraded to latest version but still no luck. We have another spare 9300 where without MAB configured on port and running show authentication session has no issue.

 

Also Mac authentication bypass (MAB) is working perfectly fine with 3850 platform so not suspecting any issue towards ISE end.

 

Not sure if something to due with hardware of 9300.
