AT-FH and AT-Wilkie Decant, 2015 - Network switches


1. Setup

1.1 Notes

  1. All switches are part of the AT network, so AT naming conventions and AT-site-specific setup notes apply.
  2. We're using new 2920-48G and 2620-48G switches, along with 2900-48G and 2610-24G-PWR switches which were previously deployed in the Forum prior to the 2013/14 network edge upgrade. All 2900 and 2610-PWR switches in the 'to be reused' pile have been reset to factory defaults.
  3. The 2920, 2620 and 2610 switches can all do DHCP-snooping and ARP-protection - which should therefore be enabled. The 2900 switches can't do DHCP-snooping or ARP-protection.
  4. The following sets of instructions will be useful:
    1. Instructions for setting up a ProCurve 2920 switch
    2. Instructions for setting up a ProCurve 2900 switch
    3. Instructions for setting up a ProCurve 2610 switch
    4. Additional site-specific instructions for setting up switches
    5. DHCP snooping and ARP protection
  5. DNS entries have already been created for all switches involved.
  6. Some switches will need to have fibre optic modules installed; others won't. The table in Section 2 lists what's needed, but the definitive information can be found in the following network diagrams:

1.2 Procedure

For each switch:

  1. Pick a switch to install from the table below.
  2. Select an appropriate model of switch from the hardware stock. Install any necessary fibre modules. Note the serial number and MAC address of the switch, and enter these in the table below.
  3. Physically label the switch, front and back.
  4. Create an LCFG profile named in the style lcfg/AS<switch no> which contains the MAC address. (The easy way is to use an existing profile as a template.)
  5. Let the profile compile and allow the resulting DHCP configuration to propagate.
  6. Rest the switch on top of the existing stack in Comms rack 2, connect port 47 (for a 2920, 2900 or 2620) or port 25 (for a 2610-24G-PWR) to port 47 of 1wb1, and turn the switch on.
  7. When the switch has finished its self-test, configure it as per the instructions in 1.1.4 above. Note that it will almost certainly be necessary to update the firmware. Current versions (at 28.1.2015) are as follows:
    Switch modelFirmware version
  8. Create switch configuration files atnet/<switch name>.pc and atnet/<switch name>.ports file which correctly reflect the configuration of the switch. (The easy way is to use existing files as a template.) You will need to refer to the network diagrams in 1.1.6 above. Make sure that:
    1. All switch interconnections are correctly labelled.
    2. For a 2920, 2620 or 2610-PWR switch: dhcp-snooping is enabled, and that all switch interlinks are trusted. (Note: don't enable arp-protection yet.)
    3. Port 47 (for a 2920, 2620 or 2900) or port 25 (for a 2610-24G-PWR) is configured as an inter-switch uplink.
  9. Push the configuration to the switch, as follows:
    1. ssh to otaka.
    2. Become root.
    3. cd /disk/home/otaka/ATnet
    4. make <switch name>.timestamp
    5. In case of any errors, fix the .pc and/or .ports files, and repeat as necessary.
  10. Check the switch front and back for any fault LEDs. Investigate if necessary.
  11. Power off the switch; remove it from the rack; box it up again; label the box; put the box in some sensible location in IF-B.02.
