How to access and configure UCC switches


This core switch is a Ubiquiti EdgeSwitch 16-XG with 12 SFP+ 10Gbps slots and four RJ45 10GBASE-T (slightly higher latency) ports. It is now the "centre" of the machine room network, connecting to:

Purchased in early 2017 as part of the revamp of our VM cluster.

It has a nice web interface at walnut.mgmt. Alternatively, a terminal interface can be opened by ssh -v [email protected] or through its serial console port. Its configuration is also accessible at


Kerosene is a Cisco Catalyst 4506-E running IOS (the *real* IOS, not the one made by the fruity company). It's configured by ssh -v [email protected] from inside the UCC network, or its serial or ethernet console ports. Its config can also be seen at

  • All wall ports in the clubroom are connected through Kerosene
  • The two new 48-port line cards are POE-enabled
  • The gigabit uplink goes through Kerosene to a separate gigabit port on Murasoi

  • Connected to #Walnut and other UCC switches via a 10GBASE-SR X2 optical module (there is one empty X2 socket)

  • It is very heavy


Lard is a Cisco Catalyst 4507R also running IOS that sits in the Guild communications cupboard opposite UWAnime. It is responsible for turning our single-mode fibre UWA uplink to Cat6 which runs back to the clubroom. It also has a downstream trunk coming back from the clubroom, which handles that side of Cameron Hall. Unigames' and UWAnime's wall ports (including our wifi in UWAnime) connect via Lard. It is also very heavy.


Curviceps can only be configured by via web interface, which is at This is on the management VLAN, which is only routed from inside the UCC. If at all possible, any machines on this switch should have either ladvd (where available) or lldpd installed so it's easier to tell what ports they're connected to.


Coconut is a Cisco 2948G running CatOS. It's configured by telnet from inside the UCC network. Coconut's config can also be seen at

  • Not in use any more, except for camps


The same model as #Coconut, this switch is only used for LANs. Every port is set to vlan 5, except port 1 which is a trunk port for connecting the loft cable. When it's connected to the network, you can telnet Its config can also be seen at


Not used anymore, except for LANs. The default IP of the Alloy, contrary to what the manual says, is The default password is admin.


Not used anymore. Bitumen is a Cisco Catalyst 4507R running IOS that was previously in the place of #Kerosene. The config of #Kerosene was lifted nearly 1:1 from Bitumen when they were swapped, only remapping ports between the different-sized line cards and accounting for the new 10G capability. When it's connected to the network, you can ssh -v [email protected]. It has dual redundant supervisor modules with serial and ethernet console ports. Bitumen is also very heavy.
