Ed, all,
1. no clue. probably the usual marketing crap.
2. NPE has a single cpu that performs all the tasks.
NSE has a PXF 'coprocessor' that can offload some tasks from the
main CPU and therefore it could perform better in some cases.
see:
AFAIK there is no special interaction between SRM and HSRP.
You might want to use the 'standby preempt delay ' feature
to be sure that routing protocols have converged before the router
is taking over hsrp active router functionality.

Not sure what exactly you want to achieve, but here are two options:
- connect a gig-ethernet port of a switch to your gig-ethernet port
of the 7600 and use a 10/100 port on the switch with fixed 10MBit
speed setting
- use traffic shaping as described in the OSM config guide:

Cisco's 25xx series uses the AMD Lance Chip for their 10Mbit

Hi Daniel,
counters are seriously broken in 12.0.21S4. Have not seen any counter
problems with 12.0.21S5 so far. This is on 7200 and 7500 routers here.
One bug open at cisco for this issue:
CSCin15495
Symptoms The output counters that are associated with an interface may
remain zero, even
Cisco1721 and VWIC-1MFT-E1 (or VWIC-1MFT-G703 if you need unframed mode).

two things that can cause the delay:
STP - Spanning Tree Protocol
Solution: 'set spantree portfast enable'
(Use it only on end-station ports)
PAgP - Port Aggregation Protocol
Solution: 'set port channel off'
(PAgP is enabled by default on EtherChannel capable links)

Not quite correct. PortFast does not disable STP. It puts a port initially
into 'Forwarding' state and then watches if loops occur. If for some reason
the port is forced into 'Blocking' state and later needs to return to the
'Forwarding' state, it has to go through the 'Listening' and 'Learning'
How is the FastEthernet 0/0 connected to the LAN ? Deferred means that the

The router tried to send the frame to the ethernet a few times but it had

check the spanning tree settings. probably the port on the catalyst is
not in forwarding state as the dhcp clients try to get their lease from
