Alright, so I am replacing an old 4507 with a new 4507. The goal is to utilize redundant uplinks to the core for seamless port/interface migration from the old switch to the new switch.
The old switch has 2 redundant uplinks on a Port Channel conn...
I'm in one of those typical situations where my organization is given 3 networks (x.x.12.x, .13.x, .14.x) but we're running out of ip addresses for clients. So I'm studying supernets and sort of going, "aha!". But I'm not sure of the practical app...
I have a 2921 router with two ports going into an ASA firewall. Both ports are assigned to the same vlan and a vlan interface is created with an IP address. This is working beautifully and we have no problems with this configuration. Now, it's ti...
I have a Catalyst 3560 PoE 8 port switch that appears to be hard broken. Plug in power and all lights stay on/amber. I've done the hold-down of the mode button procedure in various forms with no luck and what I've read given the indications is that...

Reza, thanks again. Again though...My situation would require /20 since the first four bits are used and differ when making a x.x.12.x, .13.x and .14.x. I think we're saying nearly the same thing but just wanted to clarify the slight difference fo...
Reza, Thank you for topic 2. Knowing that will probably mean we won't update the IP spaces until the next major update. For topic 1, thanks for that too but don't you mean they would advertise /20? For a x.x.12.x, .13.x, .14.x, group of previously...
Rick, Yes, I was only thinking router/switch IOS mostly because that's my specialty. I only recently started playing with Windows Server DHCP management features which are really cool. Our sys ads use that nearly exclusively as a matter of organiza...
What comes to mind to investigate DHCP configurations:# show running-config | section dhcp# show running-config | include dhcp# show run | include exclude#show run | begin exclude#show run | begin dhcp The command with "section" in it is really nice ...
