FAQ for SLAC LAN Subnets
Given a Subnet How do I find a VLAN?
The subnets and VLANs are synchronized so knowing one you know the other.
Given a building and tap how do I find the subnet?
I'm not saying the next step is easy, however it is possible. If you look in
SLAC LAN Subnets
you will find the Subnet names & addresses, # nodes, default router, mask and a description
of the Subnet.
But what you may want is that you know the building and the switch tap and want to know all
about it. Then at the top of the above page click on
Switch to Buildings. It takes you to a table of switch information in particular the
building/Location for the switch. So now you know the switches in a building.
- If you know the name of the network then you can find the buildings it
- If you click on nodes column then you can find the building and room for the network
nodes on the subnet.
Now you know the switch, so go back to
SLAC LAN Subnets.
Then at the top click on
Taps(Port_name) and search through the Port_name column for the Tap you want on the switch
in the building you want. Bear in mind the Tap (Port_name) information is kept manually
and so may be incorrect or incomplete. Hopefully if we use this information regularly, make it
easy to use, and people report errors it can be improved.
How do i find what Routers/Switches are in a given Building?
All Router/switches are Ciscos and have an OPSYS of CISCO included in the name. So click on
CANDO System Query and from the form slecet the Building number (e.g. 050), enter
CISCO% (n.b. it is case insensitive) in the OpSys field and press Search.
