+# /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
