I have an EEM applet that executes a show command using regex that works fine. However, when I converted the applet to TCL, I am having some problems with it. It's throwing an error on the line below: if [catch {cli_exec $cli1(fd) "sh run | section ip prefix-list [^ ]+ seq 5 permit $ip_prefix\.0\/24"} _cli_result] { error $_cli_result $errorInfo } TCL seems to be catching the [^ ] part of the show command and trying a substitution (trying to execute "^ " as a separate command). I could surround the show command with { } brackets but then $ip_prefix won't be substituted for the variable value. Is there any way of executing this show command within TCL? Thanks.

Alright, thanks again. It says I have insufficient permissions to view the bug though.

Thanks for the explanation. I was confused by the debug message I was getting below, but now it makes sense. *Nov 13 16:15:44.163: SNMP: Queuing packet to 10.XX.YY.50 *Nov 13 16:15:44.163: Outgoing SNMP packet *Nov 13 16:15:44.163: v3 packet security model: v3 security level: priv *Nov 13 16:15:44.163: username: user1 *Nov 13 16:15:44.163: snmpEngineID: 80000009030046513E551B00 *Nov 13 16:15:44.163: snmpEngineBoots: 19 snmpEngineTime: 68016 *Nov 13 16:15:44.163: SNMP: V2 Trap, reqid 3831, errstat 0, erridx 0 My EEM script on the snmp-server manager is able to see the v2 trap data, but the debug output is throwing out some weird errors. This was with "debug snmp packets" and "debug snmp detail" enabled. I'm not sure why it has the "Failed" message if it's still able to see the v2 trap. It also mentions v2 to v1 conversion failure, but my EEM script can see the data fine. Could you shed more light on these messages? *Nov 13 08:44:30.363: SNMP: Packet received via UDP from 10.XX.YY.2 on GigabitEthernet0/0/0SrParseV3SnmpMessage: Failed. *Nov 13 08:44:30.363: SNMP: V2 Trap, reqid 3831, errstat 0, erridx 0 sysUpTime.0 = 172168969 snmpTrapOID.0 = cEventMgrMIB.0.2 ceemHistoryEventEntry.2.223 = 131 ceemHistoryEventEntry.3.223 = 0 ceemHistoryEventEntry.4.223 = 0 ceemHistoryEventEntry.5.223 = 0 ceemHistoryEventEntry.6.223 = ceemHistoryEventEntry.7.223 = applet: ts ceemHistoryEventEntry.9.223 = 0 ceemHistoryEventEntry.10.223 = 0 ceemHistoryEventEntry.11.223 = test-data ceemHistoryEventEntry.13.223 = 0 ceemHistoryEventEntry.14.223 = 0 ceemHistoryEventEntry.15.223 = 0 ceemHistoryEventEntry.16.223 = 0 *Nov 13 08:44:30.414: dest ip addr= 10.XX.YY.50 *Nov 13 08:44:30.414: dest if_index = 1 convert_pdu:Conversion between V2 and V1 notification failed.

On the snmp-server manager router, I had to configure an SNMP user with the remote engineID of the router sending the trap like shown below. Without the right engineID, the manager was rejecting the traps and displaying "Wrong username". snmp-server engineID remote 10.XX.YY.2 80000009030046513E551B00 snmp-server group AuthPrivGroup v3 priv snmp-server enable traps event-manager snmp-server manager ASR_1002#sh snmp user User name: user1 Engine ID: 80000009030046513E551B00 storage-type: nonvolatile active Authentication Protocol: MD5 Privacy Protocol: AES128 Group-name: AuthPrivGroup

Does EEM support SNMPv3? I have written some scripts that send snmp-traps from one router to another configured as an "snmp-server manager" but it looks like they only get sent as v2. I need to use v3 for IA reasons. If it doesn't support SNMPv3, is there another reliable way of sending data between routers? I mainly need one router to know when another router gets a new OSPF neighbor and what interface the neighbor came up on. I've been using applets and I'm not as familiar as I'd like to be with TCL so maybe someone with more knowledge could tell me if there's an easier way to accomplish this in that format? Thanks.
