2505 vs. 2520

cmccul002

I tried searching for this,


What is the difference between the 2? Someone has 1 listed on Craigslist with a header of 2500 series 2520, but then in the ad it says a 2505 a few times?

* - Update.

I actually found some info:


2520 - 1 Ethernet port, 2 serial ports, 1 ISDN BRI, 2 low speed serial

2505 - 8 port Ethernet hub, two serial ports

With the 4 serial ports, the 2520 makes a good frame relay switch for a CCNA Lab (and CCNP Lab). You may need an Ethernet Transceiver to use the Ethernet Port which adds to the cost.

Since the 2505 has the built in hub, you don't need a transceiver. You can think of it as a 2501-PLUS. You can use the hub with a couple other 2500s and do OSPF DR/BDR elections. Or you can use it a a convenient place to plug in some other other 2500s if you want to use the 2505 as a TFTP server and upgrade the other 250ss.

Some people see the "8 Ethernet Ports" and assume that they get 8 Ethernet Interfaces to configure -- but they don't. The 2505 has the one Ethernet Interface you use can assign an IP and use for routing. Those 8 ports are just a common plain obsolete HUB.

The 2505 (and other HUB versions) is worth a few bucks extra over the price of a 2501 -- the cost savings on the Transceiver and the convenience factor of not needing a transceiver.
