Forum closet 100Mb 2610 edge switches - 2017/18 Upgrade

Contents

1. General notes

  1. We are replacing every (100Mb/s) 2610-48 edge switch in the Forum closets with a (1Gb/s) 2530-48G switch. Likewise, the two 'non-standard' closet edge switches b2 (a 2810-48) and 0c2 (a 2620-48) will also be replaced with 2530-48G's. The end result will be that every Forum edge switch used for conventional user connections will provide 1Gb/s ports as standard: the days of users having a mixture of 1Gb/s and 100Mb/s ports will be over.
  2. The only 100Mb/s edge switches remaining in the Forum will be:
    • the 'phones' switches: these 2610-48 switches are not being replaced in the current process;
    • the seven 2610-24-PWR PoE switches bp and 0cp[0-5]: the first of these runs the wireless access points in basement rooms other than the server room; and the others run the cameras in the InSpace Robotics area.
  3. The following sets of instructions and notes will be useful:
    1. Forum Network Documentation - specifically, the closet diagrams in the 'Edge closets' section.
    2. Instructions for setting up a ProCurve 2530 switch
    3. Additional site-specific instructions for setting up switches
    4. DHCP snooping and ARP protection
      (Note that we won't configure either DHCP snooping or ARP protection on these switches at set-up time. At subsequent installation, we will want to configure DHCP snooping on all switches immediately, but ARP protection will then need to be held off on each switch for a week or so: otherwise, valid ARP responses from active end user devices will be blocked.)
      At George's suggestion, we will try to assert both DHCP snooping and ARP protection immediately at installation time: the idea being that machines should be expected to renew their DHCP leases when their links are bounced. This will need monitoring after the first few switch installations and, if we hear about client connectivity problems, we will revert to the original scheme struck out above.

2. Setup procedure

For each switch:

  • Pick a new switch from the pile.
  • Unbox and check over.
  • Enter the MAC address and serial number in the table below.
  • rfe lcfg/FSinstall2530, and set the MAC address.
  • Install the mounting lugs.
  • Label the switch.
  • Rack up, and patch in port 47 to a suitable 'install' uplink.
  • Plug in, turn on, and watch while the self-test goes through.
  • Set up, as per the Setting up a ProCurve 2530 switch instructions.
    Note:
    • The name of the switch being installed is install2530.f.net.inf.ed.ac.uk.
    • The address to be used for SNTP server, SMTP traphost, and firmware downloads is 192.168.64.1.
    • Existing Forum 2530 switches which can be used as references for configuration details are 2a6 and 4a6.
    • There is a firmware upgrade required.
  • To download the active configuration to the switch, rfe core/install2530.pc and change the name of the portfile to that of the switch you are installing. Then ssh to dutoit, nsu, cd /disk/home/dutoit/Forum/core, and run make install2530.ets. Fix and repeat as necessary until this goes through cleanly.
  • Unrack; rebox the switch and store it (somewhere!) ready for installation.

3. Installation in the closets

Replacing the existing 2610-48 switches with the new 2530-48G switches is, unfortunately, not literally a like-for-like swap. 'User ports' will map from the old switches to the new one with no changes being necessary, but, as the following diagrams show, the available 'uplink ports' on the two models of switch differ:

Existing ProCurve 2610-48 switches New Aruba 2530-48G switches
+--+ ... +--+--+-+--+--+
| 1| ... |45|47| |49|50| <- 1Gb copper x2
| 2| ... |46|48| |51|52| <- 1Gb fibre x2
+--+ ... +--+--+-+--+--+
|<-- 100Mb --->| |<--->|
     copper       Nominal
  'user' ports   'uplinks'
+--+ ... +--+--+-+--+--+
+ 1| ... |45|47| |49|51| <- 1Gb fibre x2
+ 2| ... |46|48| |50|52| <- 1Gb fibre x2
+--+ ... +--+--+-+--+--+
|<--- 1Gb ---->| |<--->|
     copper       Nominal
  'user' ports   'uplinks'

Specifically note that ports 49 and 50 on the new switches are unavailable for copper uplinks/interlinks.

So: for the existing 2610-48s, the uplink ports are generally 49 and 50; for the new 2530-48Gs, these will have to be mapped to 47 and 48 instead. Likewise, for those switches with more than two copper uplinks/interlinks (namely: 2a2, 2b1 and 2c3), the same pattern will apply: (the new link) = (the old link) - 2

(Fibre uplinks/interlinks - for the few 2610-48s which have them, namely: b0, b1, 0a1 and 2a2 - are unaffected.)

Network diagrams, and port labels in .pc files, will all need updating to correctly show the new configurations.

Note that our default configuration for the 2530s (i.e. the file core/install2530.pc) correctly sets up ports 45, 46, 47 and 48 (copper), as well as 49, 50, 51 and 52 (fibre) as interlinks/uplinks.

4. Add the new switches to the inventory

At the very end of this process - i.e. when all switches involved have been installed, and are in service - use the /afs/inf.ed.ac.uk/group/cos/utils/create_system script to add the serial number of the switch to the inventory:

create_system --serial <serial number> --hostname <fqdn>
If this works correctly, fill in the relevant 'In Inventory' field in the tables below.

(In order to avoid any complications, note that these inventory additions indeed need to wait until the very end of this work: I am not sure whether or not the current switches of the same names are already in the Inventory.)

Comment: The above doesn't work. E.g

[jive]idurkacz: /afs/inf.ed.ac.uk/group/cos/utils/create_system --serial CN73FP62RH --hostname b0.f.net.inf.ed.ac.uk
Hostname b0.f.net.inf.ed.ac.uk is already in use at /afs/inf.ed.ac.uk/group/cos/utils/create_system line 184.
[jive]idurkacz: /afs/inf.ed.ac.uk/group/cos/utils/create_system --serial CN73FP62L4 --hostname b1.f.net.inf.ed.ac.uk
Hostname b1.f.net.inf.ed.ac.uk is already in use at /afs/inf.ed.ac.uk/group/cos/utils/create_system line 184.

So some other approach work is needed ...
