ip access-list-name 100 "list #100"
ip access-list 100 1 deny icmp any any
ip access-list 100 3 deny tcp any eq 161 any eq 161
ip access-list 100 4 deny tcp any eq 445 any eq 445
ip access-list 100 5 deny tcp any eq 2745 any eq 2745
ip access-list 100 6 deny tcp any eq 5554 any eq 5554
ip access-list 100 7 deny tcp any eq 9898 any eq 9898


Above is Avaya P332GML layer 3 switch ACL
The idea is to block any "ping" activity from user

Last week, my colleague install new AntiVirus Server (Hauri)
The problem is client cannot get update from the server
Server located at Vlan2 and client located at vlan3 & vlan4
When i disable the ACL function, the client can get the update from the server smoothly.

Is it because of my ACL problem?
Need your guide..Thanks

I am not sure about the Avaya L3 Switch.
Try the following at end of the ACL give the

ip access-list 100 permit tcp any any
