Cisco MLS SUP720 issue

[vinoth.kumar]

Hi,

In our network intially we had 800mb of traffic flow between our site1 to site2 with point to point 1 gig connectivty in the cat 6500 with SUP 2 on both the site

on 1 site we upgraded the SUP2 to SUP720 last night and we din see any issues but when 600mb traffic flow started in mid day we had a issue that from site 1 to site 2 no connectvity isssues but icmp from site2 to site1 is giving issue

the interface traffic size

5 minute input rate 637419000 bits/sec, 464796 packets/sec  site2 to site1

5 minute output rate 630223000 bits/sec, 465577 packets/sec site1 to site 2

we suspecting some interface traffic ratelimit issue since we din face the issue in the morning when we have 500mb of traffic

we have the below config on our new SUP720 catalayst whether this will be rootcause

no mls acl tcam share-global

mls aging long 64

mls aging normal 32

mls netflow interface

mls rate-limit unicast cef glean 20000 60

mls rate-limit unicast ip rpf-failure 500 10

mls rate-limit unicast ip icmp redirect 0

mls rate-limit unicast ip icmp unreachable no-route 500 10

mls rate-limit unicast ip icmp unreachable acl-drop 500 10

mls rate-limit unicast ip errors 500 10

mls rate-limit all ttl-failure 10 1

mls verify ip length minimum

mls cef error action reset

thanks
