Thanks for the suggestion. When I try this:
Target[vlan-10-hosts]:
CnTWaLK.1.3.6.1.2.1.17.4.3.1.1&CnTWaLK.1.3.6.1.2.1.17.4.3.1.1:public\@10@@10.0.1.2:::::2
I receive the error shown below, so it doesn't appear that the string
is being escaped properly because it's interpreting the backslash as
part of the community name and treating the first '@' as the delimited
between community name and host. Any other ideas?
SNMP Error:
send_query: Invalid argument
SNMPv1_Session (remote host: "10" [0.0.0.10].161)
community: "public\"
request ID: 2117844684
