Thanks for the advice. I knew how to achieve that from the command line.

I didn't make it clear from my post that from the command line but my
question is when user invokes trap sink via "SNMP Monitor menu" from the
tkined tool, it doesn't offer the same flexibility.

I spend some time digging around last night and came up with this
workaround:

Make global snmp_protocol visible in TrapSink procedure (found in
snmp_monitor.tcl) like this (see diff -cw below) then it can be
controlled via "Set SNMP Parameter" option.
