43. What is the name standard for network equipment on BMC.

See also: How are the network sockets identified?
See also: What Internet bandwidth does the university have?
See also: Some Cisco switch commands

Unfortunately there are several systems still in use for naming the network equipment at BMC.

Name standardYearIntro- duced byExplanation
? 1976- BMC Naming of old terminal network blessfully forgotten.
? 1986- BMC Naming of old ethernet network blessfully forgotten.
C5:2 1998 BMC The first C5500 fast ethernet twisted pair switches were named named after the cross connect cabinets where they were located.
C5:2-2 2000 BMC With the addition of C2980 and C3500 switches, the naming included a serial number for each cabinet.

Cluster_A1-1
Cluster_A1-1-1
C1-2-2mem1
C3:3-3-Mem_1

 2005 UUIT

At some point in time the switches were clustered C2950 in order to minimize the use of IP-addresses.

  1. Problem: It is getting really hard to know which switch is which with all members and clusters.

A3:1_Poe-Manager
A3:1_Poe-Manager-1
A3:1_Poe-Manager-2

 2007 UUIT A new naming standard for PoE switches showed up with the need to identify the PoE capable switches.

C2960S-C6-3-319c
C2960S-C5-3_3
C2960-C6:013b
C5K-C7-3
C5K-C7-2

 2007 (?) UUIT At some point in time the switch model was introduced in the name, perhaps to easier identify the switches, at least the new ones. However, several different seperators where used. When switches where not put in cross connect cabinets the room number where introduced.

MODEL HOUSE FLOOR [NUMBER]

MODEL HOUSE ROOM

BMC-A9-1-3 2011 BMC A prefix was introduced to separate BMC-switches from other switches. The switches were still named after the termination of the cables in the cross connect cabinet. The naming was:

CAMPUS HOUSE FLOOR NUMBER

  1. Problem: Do not scale to several cross cabinets (racks).
BMC-D9-3-01b-8 2013 UUIT The cross connect cabinet room number where used instead of the network socket termination rack. The idea was to use the same system all over the university.

CAMPUS HOUSE FLOOR ROOM NUMBER

  1. Problem: the cross connect cabinet rooms change house and room number even if they are vertically located above each other.
  2. Problem: the markings on the switch do not match the markings on the network socket.
BMC-D11-0-09a_48-1 2014 UUIT

Server room required naming based on racks introducing a new system:

CAMPUS HOUSE FLOOR ROOM RACK NUMBER.

  1. Problem: by only looking at the switch name it is not possible to know what VLANs are on it. The BMC-HALL switches should probably have used another prefix than BMC. Perhaps a router prefix?
BMC-C11-3-D302-3 2015 BMC

The introduction of room numbers makes it harder to figure out what switches are located in what cross connect cabinet. Introduce the rack for the cross connect cabinets like the in the server room.

CAMPUS HOUSE FLOOR RACK NUMBER.

  1. Problem: Redundant floor number, both in the FLOOR and in RACK.
  2. Problem: New flexstacked switches appearing at this time share the same network name but introduce a new physical name making it hard to identify which network socket it is.
  3. Problem: Large flexstacked switches may sit in two racks.

BMC-C1-3-D302-S-1
BMC-C11-3-D302-S1
BMC-C3-2-D202-S1

2016 UUIT

No problem, just add a number telling it is a stack and then a number for for each member in the stack! Or perhaps a slash?

CAMPUS HOUSE FLOOR RACK ROOM "S" NUMBER.

  1. Problem: Not the full room number, the room numbers are always three numbers and perhaps a letter.
  2. Problem: Redundant floor number, both in the FLOOR and in RACK.
  3. Problem: Still a bit hard to figure out what name is a switch name an what is a flexstack number...

Switches are put in DNS! Great! Unfortunatelly this introduced a new name with the FQDN and also a new name not always exactly as the old switch names due to partial rename.

Using the same naming as the Wi-Fi hotspots introducing block (kvarter) in the name via Byggnadsavdelningens register.

BLOCK HOUSE (with extra zero prefix)FLOOR ROOM NUMBER.

  1. Problem: introduce new prefix fal01- instead of bmc-
  2. Problem: the cross connect cabinet rooms change house and room number even if they are vertically located above each other.
  3. Problem: the markings on the switch do not match the markings on the network socket which references to the cross connect cabinet.
  4. Problem: The block name (fastighet / kvartetsnamn) for BMC is ROSENLUND. FALTLÄKAREN is the old Magistern or Kunskapsskolan. The plot is Kåbo 1:10.
  5. Problem: The NUMBER is not unique for each cross connect cabinet.
  6. Problem: Introduce a leading 0 in front of floor number.
