Restrict access to a port by IP Address Catalyst 3550
Joe...The 3550 appears to have considerable multilayer capability, I have never seen one, [fairly new]. here's a cut from Cisco CCO on the issue of layer 3 ACL's, filters,etc. config info and such....tom http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/1219ea1/3550cr/cli1.htm#xtocid51 -
Native Vlan
A good question....I guess you already know the definition, "native VLAN" refers to a VLAN whose frames are NOT encapsulated with tagging information under 802.1Q trunking rules. Further questions would be, without vlan id, would it be trunked at all? Also, with pruning, would any... -

How do I add other switches to my cluster ?
Hi, That sounds like a very general question. I guess you are running Cisco clustering software., CMS and/or SNMP to manage the cluster I grabbed these links to some clustering stuff on Cisco's CCO disks Tom http://www.cisco.com/warp/public/cc/pd/si/casi/ca3500xl/prodlit/swclu_ov.htm... -
Blocking a MAC on a C2980 FastEthernet port
The Cat 2980G is a Pretty smart switch. You did not mention who or what else should have privleges with your blind port. It sounds like you would want to assign it to its own Vlan, and group it with whomever should have access. Also with VTP you may cross switches and maintain Vlan... -

How to disable telnet logins to a Cisco Catalyst 3500 series switch?
Well, here's my humble opinion...I'm guessing it's the 3500XL that you have. I don't think it will support MLS functions and will not support access filters, ( Telnet being a layer 4 function, port 23). You can lock out "all" virtual terminal access by not providing a vty login... -
Ultra1 crashing to prom
Yes, A problem w/ the Keyboard or cable could cause trouble. Any failure that results in breaking the KB connection will take the machine to the OK prompt. However the prompt should show "type Go to resume". That is where you end up following a "stop A" sequence, which... -
Ultra1 crashing to prom
You've probably solved this by now. For what it's worth, the early Ultra1's had a cooling fan on the cpu that caused a lot of trouble.(noisy, slow down, run a while and stop) cpu would get hot and crash the box...New U1s have a big heat sink, no fan....
