We have a 6513 Catalyst router running 12.1.(27b)E1 that handles all
our network traffic in our facility.  Recently, My supervisor has
expressed an extreme interest in prioritizing our traffic by IP
subnet.  Group A owns the router.  Group B is a tenant and does not

This may seem like a trivial question, but the last time I tried it,
it didn't work.
I only have a small window to test, so wanted to see if I am doing
everything correctly.

Is it always necessary to enable vtp pruning. And under what condition
will you enable it. Thanks.

I have Multiple ISP Internet links and Multiple Valid IP ranges from
each ISP.
For Example let my First Range be 20.10.10.0/24 from ISP-A
let my Second Range be 30.10.10.0/24 from ISP-B. Traffic from First

I have an interesting problem.  To my knowledge, the configuration of
one of our customer's Cisco 877 routers has not changed.  However,
their Internet connection is not working.  The router is syncing with
the ISP, as indicated by the CD light going solid, but the connection

How do I copy the config from one 3560 Cisco Switch to another, it
needs to be exactly the same.
I am familiar with ProCurve Switches, there was a neat little program
to do this.

I know this is a weird question, but someone asked me and I thought
I'd throw it out.  I have no intention of implimenting it to see, but
it started me thinking.
A client wanted to know if he could run a dot1q trunk through a hub.

I have a main frame (10.0.0.1) that sends a print job to a specific IP
(192.168.1.25) for printing. We have changed our internal network from
a flat to ospf achitecture. The IP for the internal host has changed.
Is there a way I can redirect the traffic heading from 10.0.0.1

I have a problem with one end of a GRE tunnel not comming up.
I have an IPSec LAN 2 LAN VPN between two sites. Site A, the VPN
terminates on an ASA 5520. On site B it terminates on an ISR 3825

It is my understanding that the gigabit spec requires auto-negotiation, so
what does turning it off really do?

Hey everyone,
I'm interested in setting a delay on an ethernet interface so that the
router only transmits the packet/frame after a set time. Any idea how
this is done?

I've tried googling this messages, but I've not found a good answer:
%SPANTREE-5-EXTENDED_SYSID: Extended SysId enabled for type vlan
Can anyone give me a short brief about this messages? Anything to worry
about?

I have the old 3550 and 3560 switches in my network. I want to connect
them using  fiber. Where can I find information regarding the types of
GBIC to use and if I need to use either LC or SC fiber cables. Thanks.
