[nsp] Cat6509 MSFC1 interface stats.

[Rubens Kuhl Jr.]

MLS seems to be disabled on one MSFC(module 15, first slot), but not on the
other MSFC(second slot). Easy solution: log on to the second one and disable
it. Long solution: use an IOS version that supports MSFC config syncing.

BTW, what code versions are running on Sup and MSFC ?

| Thanks for the info about CEF... Wasn't aware of that.
|
| MLS is disabled globally on the MSFC:
|
| #sh mls rp
| ip multilayer switching is globally disabled
| ipx multilayer switching is globally disabled
| ipx mls inbound acl override is globally disabled
| mls id is 0030.9633.1c6c
| mls ip address 0.0.0.0
| mls ip flow mask is unknown
| mls ipx flow mask is unknown
| number of domains configured for mls 0
|
| I just noticed something that only serves to confuse
| me more, though.  MLS is enabled on the SUP itself:
|
| Cat6509=> (enable) sh mls
| Total packets switched = 1387031763
| Total Active MLS entries = 83
|   MSFC x.x.x.2 (Module 15) entries = 0
|   MSFC x.x.x.3 (Module 16) entries = 83
| Long-duration flows aging time = 1920 seconds
| IP Multilayer switching aging time = 256 seconds
| IP Multilayer switching fast aging time = 0 seconds,
| packet threshold = 0
| IP Current flow mask is Destination flow
| Active IP MLS entries = 83
| Netflow Data Export version: 7
| Netflow Data Export disabled
| Netflow Data Export port/host is not configured.
| Total packets exported = 0
|
| Any idea how is MLS working (it seems to be working
| based on the above, and a 'sh mls entry' does indeed
| show entries) if it's disabled on the MSFC?
