Title: RE: trapsess -e <Engine-Id>

Hi Thomas,

Thanks for the reply.

I tested trapsess directive with EngineId less than 19 bytes, I think you know that snmpTargetParamsTable will have the values popualted with corresponding trapsess directives in snmpd.conf

If I use the length of Engine-Id less than 20 (-e option) then there are no entries for snmpTargetParamsTable.

The following are the details for my environment. I tested this on Linux/Fedora platforms.

snmpd.conf has the following entries.

*********************************************************************************
trapsess -e 0x900003ddf15414344452 -v 3 -u admin -a SHA -x AES -l noAuthNoPriv 10.201.114.135 -Ci

trapsess -e 0x000000a1030020ED0DD2 -v 3 -u myuser -a MD5 -A mypassword -l noAuthNoPriv 10.201.114.137 -Ci
*********************************************************************************
Some sample O/P for snmpTargetParamsTable query.

[EMAIL PROTECTED] snmp]# snmptable -v2c -c wimax 10.201.114.135 snmpTargetParamsTable

RFC 3411 specifies SnmpEngineID as

   SYNTAX       OCTET STRING (SIZE(5..32))

so there shouldn't be a requirement for a 20 byte minimum.
