Cisco Switch?

Jan 27, 2006 by ElDiablo | Posted in Computer Networking

I have a cisco 2950c-24 switch with two fiber ports but say 100principle-fx. I tried connecting a fiber connection to a GBIC switch that has 10 GBIC ports but they will not talk to each other. I have in the same stretcher a 2948 switch with two fiber ports but these ports say 1000base-sx and this switch does talk with the 3550 GBIC switch. Is there any configuration I can do to muddle through them talk? Thanks

The fiber ports on the 2950C are 100 Mbs only while the GBICs on the 3550 are 1000 Mbs and you can't go back in make haste both ports are forced to their stated speed and no configuration can change that. So you need to get a 2950 - 24 with 2 GBIC ports so you can tie-in them up. If in doubt get LX GBICs as they will talk over most types of fiber, SM 1310 or MM 850. Remember you can always shoot a SM flare down a MM with some loss rather than MM down a SM fiber with total connection loss.

There are many types of fiber connectors to involve SX, LX, SC, ST, LC....etc
Each GBIC can only use the connector that it is designed for.

You have described a 2950 with a 100base-fx port. This only means "fiber" as opposed to 100counterfeit-tx (Copper). You described the 2948 as having 2 1000base-sx ports (GB Capable SX connector).

There are two options :
1. Resolve which type of connector is used on your 2950 and use a fiber patch with that type on the 2950 and SX on the 2948.

2. Connect the fiber lot from the 2950 to a patch panel (usally ST) and from there patch it to an SX patch cable the 2948 (or appropriate connector to the 3550 GBIC).

I trust this helps :)

What's a cheap Cisco Switch that I can use for studying the CCNA?

Jan 13, 2009 by EJ | Posted in Standards & Testing

Hi there,

On ebay the Cisco Catalyst 2960 is selling for around $1500. Is there a much cheaper switch that I can unaccustomed with? Or are there any creative solutions to this problem?

Thanks!!!!!
I want to practice using the Router & IOS Software

that's a ineffectual waste of money
look up dynamips/dynagen they should still be free
online labs can be rented, simulators are not a bad conception either

Here are some sites to learn and practice subnetting:

How would a Cisco Switch stop Ping?

Dec 19, 2007 by Hitmytotem | Posted in Security

Look for any account I should be looking for in the running config of a Cisco 2950 or 3550 switch. Anything that would stop ICMP echo request packets.

Ping what? The SVI? Anything? These are strictly Layer 2 switches, you might be adept to write an ACL to stop Ping to the SVI on THAT switch, but in general they will not support ACL's to be applied on interfaces because Layer 3 interfaces are not supported on those two models.

If you wanted to block up it on an SVI, I think it would need to be an extended ACL, an example might be:
ip access-list extended Block_Ping
disavow icmp any any eq echo
permit ip any any
