so how? I checked most mib files with BGP info in it but couldn't find
anything.

Hi Gary,
I'm not completely clear on what your requirements are, but you may want
to have a look at the 'local-as' bgp neighbor option. Will let your

If you're determined to use SNMP and snapshots, you may wish to take a
look at the NetFlow MIB, which lets you get a snapshot of the NetFlow
table.
Any idea if there is an equivalent in SFlow? I have been looking around the
Sflow Mib but didn't find any usefull

Jon,
You might want to take a look at Catalyst 4948, which might present a
better feature parity/richness and might be a better match for your
requirements.
The normal 4948 would do IPv6 in software, so it really depends on how
wide you expect your deployment to be, but you can take a look at the

If you have Spanning tree enabled on the CISCO (which is default )

This will speed up initial boot of machine instead of going through

Well this sounds like your problem.

Ports are already configured for port-fast. Like I said, it seems that
after disabling PoE on the port everything works fine.

I'd check the IOS version against the model of SFP to make sure that
it's supported (though I imagine it will be). I'd agree with the other
guys in saying that it's likely counterfeit. Do you get it from a
reputable vendor?

Sorry, but this sounds like a won't work.
Your server is depending on sending spoofed packets. If this was on a
local VLAN, you could simply put if2 in the same VLAN as the sniffer-if

RSPAN, so I guess the traffic isn't local,
