Subject: MIB-II on proxied chassis entities.
Howdy, I'd like opinions about the structure of MIB-II on proxied chassis entities. For example, say the Chassis Entity Table contain the following entries: Agent: chasEntityCommunity "public" chasEntityIpAddress 16.21.16.128 Proxied Entity 1: chasEntityCommunity "lineCard1" chasEntityIpAddress 16.21.16.128 Proxied Entity 2: chasEntityCommunity "lineCard2" chasEntityIpAddress 16.21.16.128 so the agent is proxying for "lineCard1" and "lineCard2". >From past discussions, the minimal MIB-II implementation has the system and snmp groups. One could: 1) Keep a per proxied entity system group and a per proxied entity snmp group. So, the agent's snmp group counters count only those messages directed at 16.21.16.128 on community "public". lineCard1's snmp group counters count only the snmp messages directed at 16.21.16.128 on community "lineCard1". Similarly, lineCard2's snmp group counters count only those messages directed and 16.21.16.128 on community "lineCard2". In other words, there is an individual snmp group per community. 2) Keep a per proxied entity system group, and a per proxy agent snmp group. So, the agent's snmp group counters count all snmp messages directed at 16.21.16.128 regardless of community. The counters are the sum of all snmp traffic to "public", "lineCard1", and "lineCard2". The view of "public" contains the system, if, ip, etc., and snmp groups. The view of "lineCard1" and "lineCard2" contains the system and snmp groups. The later is easier to implement. Is it less useful? Is it more confusing to users? Is one approach clearly better than the other? -Shawn
