# 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





# 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

dpavlin@black:~/dell-switch$ ./find-port-for-mac 00:1e:8c:0a:49:3c # eeepy eth0

dpavlin@black:~/dell-switch$ ./find-port-for-mac 00:80:c8:37:6d:76 # eeepy eth3
sw-e300 1 00:80:c8:37:6d:76 17
