Good day, folk.
In "How to display the EOBC error counters in the Catalyst 6500 series switches and a definition of the EOBC interface" document here on support forum stays that
The Ethernet Out of Band Channel (EOBC) is a half duplex channel that services many functions, which include the Simple Network Management Protocol (SNMP) and the packets that are destined for the switch.
Previously i were thinking that EoBC used only for SCP and SLP protocol. In addition i found other article (but not on cisco site, heh) where stays that
The Results bus is a control plane, while the C (EoBC) bus is more of an "admin plane", thus you will never see data packets (such as CDP, SNMP, etc.) going over the R or C bus.
So there is a big contradiction between those two statements. Can somebody prove one of those and if first one right, what meaned under the
packets that are destined for the switch
in it? SCP and SLP or other traffic as well?
Thanks in advance!
This problem usually occurs due to these circumstances:
SCP is the protocol used for communication from SP to non-DFC line cards through Ethernet-out-of-Band Channel (EOBC) on the Catalyst 6500. . SCP or Keep Alive Polling failures could represent communication issues between the supervisor and line card.
Let me know if you required any further information on this and I would assist the same.
*Plz rate all usefull posts.
Ideed, I require futher information.
All you post here i already red, i even adduce link to this article in my initial message.
But even if take that SNMP pass over EoBC, I still wondering for - what type of packets/protocols use EoBC apart from SNMP, SCP and SLP?
Besides is there any possiblity to mirror traffic passed over EoBC?
