Stop the %BMP-5-BMP_DISCOVER: DHCP DISCOVER spam on a new F10 switch

When configuring new switches, the flood of these messages over serial console can be quite intrusive…

This is because F10 ship in “Jumpstart mode”, run this command to disable it ( reload the switch after executing it).

FTOS# reload-type normal-reload

Setup a stack on Force10 S4810

Set stack switch priority on the switch you want as master

stack-unit 0 priority 14

Enable the stack groups, this will make a specific interface a stack-port ( see below for a mapping of ports to stack-group ).
In this case I am using the 40gig ports ( port 48 ). Once enabled you will not be able to use that port.

stack-unit 0 stack-group 12

accept the prompt/warning

Setting ports Fo 0/48 as stack group will make their interface configs obsolete after a reload.
[confirm yes/no]:yes

Save your config and reload ( both switches )

check your configuration

sh system
sh system stack-ports

Physical port to stack-group mapping

10G ports

Ports 0-3 – stack-group 0
Ports 4-7 – stack-group 1
Ports 8-11 – stack-group 2
Ports 12-15 – stack-group 3
Ports 16-19 – stack-group 4
Ports 20-23 – stack-group 5
Ports 24-27 – stack-group 6
Ports 28-31 – stack-group 7
Ports 32-35 – stack-group 8
Ports 36-39 – stack-group 9
Ports 40-43 – stack-group 10
Ports 44-47 – stack-group 11

40G ports are numbered 48, 52, 56, and 60

Ports 48 – stack-group 12
Ports 52 – stack-group 13
Ports 56 – stack-group 14
Ports 60 – stack-group 15

Sangroup member goes offline due to wrong DCB vlan id

We had a weird issue with a brand new sangroup we configured.
The san members saw each other, and once we applied a CDB vlan ( via Group Configuration -> Advanced ) we lost one of the san groups.
After fumbling around with the actual switch configurations and getting no where I used the

show grpparmas

command only to see that the san group members had the wrong dcb vlan:

SAN01> DCB: enabled Def-DCB-VLAN-Id: 1001
SAN02> DCB: enabled Def-DCB-VLAN-Id: 0

From there it was easy, since we could not configure the “offline” san unit, we ssh’d in and used the following command to set the correct vlan.

grpparams dcb def-vlan-id 1001

Once we did that, everything came back to life.

Dell Equalogic commands

show member

This will print out your san group members with some basic info, as seen below.

Name Status Version Disks Capacity FreeSpace Connections

SAN02 online V7.0.5 (R3 48 31.69TB 1.58TB 10

member select SAN01 show eth

This will print out status of your network cards

APT/Dpkg options I always forget

Remove a package and its dependencies

apt-get autoremove packagename

Install a specific pkg version

apt-get install package=x.x.x-version

Purge config files of remove packages

dpkg -l |awk ‘/^rc/ {print $2}’ |xargs sudo dpkg –purge
