# manage Dell switch running-config in git

dpavlin@black:~/dell-switch$ ./sw-running-config.sh sw-dpc


# /dev/shm/port-status

Collect information about port status using snmp

dpavlin@black:~/dell-switch$ ./snmp-port-status.sh sw-core # single switch

dpavlin@black:~/dell-switch$ ./sw-port-status.sh # all switches

This will populate /dev/shm/port-status/ and manage changes in git

You can grep for ports on switches since format is "switch port ...."

dpavlin@black:~/dell-switch$ egrep ' (15|22) ' /dev/shm/port-status/sw-dpc 
sw-dpc 15 g15 1000 up ethernetCsmacd [sw-baraka]
sw-dpc 22 g22 100 up ethernetCsmacd [PIX-eth1]

You can also grep only for sw-name and get both uplink port (if in description)
and ports from switch:

dpavlin@black:/dev/shm/port-status$ egrep sw-baraka * | head
sw-a200:sw-a200 22 g22 1000 up ethernetCsmacd [sw-baraka]
sw-baraka:sw-baraka 1 g1 1000 down ethernetCsmacd
sw-baraka:sw-baraka 2 g2 1000 down ethernetCsmacd
sw-baraka:sw-baraka 3 g3 1000 down ethernetCsmacd
sw-baraka:sw-baraka 4 g4 1000 down ethernetCsmacd
sw-baraka:sw-baraka 5 g5 10 up ethernetCsmacd
sw-baraka:sw-baraka 6 g6 1000 down ethernetCsmacd
sw-baraka:sw-baraka 7 g7 1000 down ethernetCsmacd
sw-baraka:sw-baraka 8 g8 1000 down ethernetCsmacd
sw-baraka:sw-baraka 9 g9 1000 down ethernetCsmacd

Get additional OID from switches:

dpavlin@black:~/dell-switch$ ./snmp-port-status.sh
Usage: ./snmp-port-status.sh hostname ifAdminStatus BRIDGE-MIB::dot1dStpPortState ifInErrors ifOutErrors ifInDiscards

If it's started without any arguments, script will show additional OIDs which might be interesting to include along
default ones. So, to pull ifAdminStatus on all switches we can do something like:






# ssh auto-login script for Dell switches

./ips | xargs -i ./dell-switch.pl {} "show bridge address"

./ips | xargs -i ./dell-switch.pl {} "show interfaces status"

./ips | xargs -i ./dell-switch.pl {} "show running-config"

This will save all commands executed to git repository under log/

However, somethimes you just need to execute few commands but don't want
log output (if configuring switches in batch, for example). You can do
that by setting NO_LOG enviroment variable like this:

grep -A 1 sw-lib /etc/munin/munin.conf | grep 10.20 | awk '{ print $2 }' \
| NO_LOG=1 xargs -i ./dell-switch.pl 'snmp-server community public-or-not ro view Default' 'exit' 'copy running-config startup-config'


To use fans script first pull show system from all switches:

./ips | xargs -i ./dell-switch.pl {} "show system"


Backup switch configuration to tftp server:

./ips 1,2 | awk '{ print "./dell-switch.pl "$1" \"copy startup-config tftp://10.20.0.253/backups/"$2".config\"" }' | NO_LOG=1 sh -x


To use snmp* utils, create snmp.conf with:

COMMUNITY=my-comminity-or-public


# Find mac address on network

collect all mac addresses using snmp

dpavlin@black:~/dell-switch$ ./sw-mac-port.sh 

find interesting mac

sw-e300 1 00:80:c8:37:6d:76 17
# mac 00:80:c8:37:6d:76 on 41 switches
