Blocks on SNMP (Port 161) stop printing

[brianprice]

Applying an ACL to one of the VLANs on a 5513 has disabled all printing between this VLAN to others. The ACL is configured only to block port 161 SNMP, and allow everything else. Hence, the lines are as follows:

access-list 111 deny udp any any eq snmp log

access-list 111 permit ip any any

access-list 111 permit tcp any any

access-list 111 permit udp any any

access-list 111 permit icmp any any

This ACL is applied to a VLAN interface:

For instance:

#conf t

(conf)# int vlan 154

(conf-if)#ip access-group 111 in

Can anyone tell me why this would disable the printing between the workstations on this VLAN?

Thanks so much

No, that should work. You'll probably need to debug it with TAC.

What kind of printers do you use? Some printer management tools like HP Jetadmin use SNMP as well.
