There is a lot of talk about how PFC makes Ethernet loss-less and suitable
for FCoE or ISCSI. My question is, for single-type-of-traffic interfaces,
for example ISCSI arrays connected to a Ethernet switch. Why doesn't
traditional PAUSE based flow control give the same level of loss-less
Really it comes down to the fact that you can pause all traffic except for
your iSCSI (if identified properly) and FCoE traffic.. With PAUSE frames
everything gets paused on that link, including your storage traffic.

pause will normally cause head-of-line blocking on congested links because
it applies to all traffic on a link. pfc will attempt priority based frame
delivery and can be less disruptive depending on traffic profile. In
The BGP session went down, and stayed down for about 3 min, as if there was
a problem for TCP to establish a session back on. It happened during DDOS,
before and after that this session never dropped. There's nothing in logs
except that notification was sent since the hold timer expired.

Hi NSP,
Is anyone familiar with the 3800X and why we are unable to configure EIGRP for
IPv6 even though its clearly stated in the configuration guide as available?

Hi Sander,
Thanks for the reply, that was our first thought as well... we tried, but only
the default sdm template was available to us. I've just had a scan through the
datasheet and noticed this;
Switch Database Management (SDM) templates (with the Scalability license only)
This is a £3000+
Out of interest, are your transit access interfaces sub-rate?

You might want to double-check that your iACLs are up-to-date, that you've
enabled GTSM, that you've enabled CoPP, etc.

Hi Steve,
Debated this with Cisco a while back - apparently more aimed at PE
edge, so less routing capabilities more MPLS.
Last time I asked the scaled metro license was only for scale - below
from an SE 6 months or so
What version of code are you running?

Needless to say, one needs routing capabilities to support
MPLS.
