Zhooibaal\’s house of the unholy


Home => Cisco

Welcome to my Cisco page, here I will show all the network equipment that I own from the brand Cisco Systems. “Why only Cisco systems?”, you may ask, but that question is rather easy to answer: “Because it rocks!”. Not just that, it also fits within my studies, so they are a very handy set of tools to practice with.
Other equipment is mostly of no great value to me anyway, so I’ll stick to the Cisco stuff.
Let’s first start of with the small things I have:

The first picture is a transceiver which is used to use a AUI port as an ethernet port which is mentioned later on. The second picture is a DCE/DTE back to back cable used to connect 2 routers using the serial interface.
And one last picture before any further details, everthing together stuffed into my little stereo cabinet which is no longer being used as a stereo cabinet.


First a few words about the routers I have:

  • 1601R
  • 2501
  • 2514


This must be by far the least interesting of the lot. It has the lowest memory capicity, lowest amount of interfaces, worst formfactor and it’s the only one I have with an external power supply, but, now comes the big “but”, it is also the only modular router I have. This means that it has space for something extra to be added to it’s current layout.
Anyways, what makes this one a valueable asset to my lineup is that it simply is a router which can be used to practice. It’s inability to do almost anything the other 2 can due to older software makes it only interesting as just an extra node in the network though.

2500 series

Both the 2501 and the 2514 are more usefull than the 1601R (or any 1600 series router for that matter). Allthough both the 1600 series and the 2500 series routers are only 10mbit, the 2500 series have some serious advantages over the 1600 series:

  • formfactor, 19″ rack mountable
  • dual serial interfaces
  • higher available software versions
  • more routing functionality
  • bigger memory

The dual serial interfaces are a very handy addition when you want to connect more than 2 routers to one another without wasting ethernet interfaces. Serial interfaces are used for WAN connections rather than LAN connections and that can also be preferable to connect multiple routers to one another to simulate a WAN (Wide Area Network) or internetwork.
Here are some pictures of them.



As you can see, these routers have no standard ethernet interfaces, but AUI interfaces instead. These can be used as ethernet interfaces when a transceiver is attached to them.
The only difference between the 2501 and the 2514 is that the 2501 has only 1 AUI interface and the 2514 has 2.


I only have 1 Cisco Systems switch as of yet, but it’s quite a good one, so currently I have no need for more.
It’s a Catalyst 1924 enterprise. Allthough it’s only 10mbit it’s really fast enough for what I use it for. It has 24 10base-T ethernet ports which can freely be distributed over a virtually unlimited amount of VLANs. A VLAN is a virtual LAN and can be used to segment a network, protecting clients from one VLAN from access by clients on another VLAN.
Besides the 24 10base-T ports it also has 1 100base-T ethernet uplink port and a 100base-T optical fiber uplink.
