snmp THROUGH css

[shathaway]

Hi,

I am trying to monitor some hosts, using SNMP, behind our CSS11501.

I Read The Fine Manual, and eventually got

something working, but it broke DNS on the hosts.

I removed the Group statements, and now DNS works, but not SNMP.

Anyone have any clues on this? the relevant config info is below.

Thanks in advance.

flow-state 161 udp flow-enable

!************************** SERVICE **************************

service APP1

ip address 192.168.16.75

redundant-index 90

active

service APP2

ip address 192.168.16.77

redundant-index 89

active

!*************************** OWNER ***************************

owner BOGUS

content mgmt1

add service APP1

vip address 192.168.16.18

protocol udp

active

content mgmt2

add service APP2

vip address 192.168.16.19

protocol udp

active

!*************************** GROUP ***************************

group snmp-app1

vip address 192.168.16.18

add service APP1

active

group snmp-app2

vip address 192.168.16.19

add service APP2

active

you should try to add to the group config 'portmap disable' and also add

'flow-state 53 udp flow-disable nat-enable'

or

'flow-state 53 udp flow-enable'

If this does not work, capture a sniffer trace font-end and backend and verify what the CSS does with the DNS traffic.
