  • 1.  show interface command with options

    Posted 01-12-2023 13:14
    Hello, 

    I'm trying to figure out if there is a syntax to use to show interfaces that are physically down, and if they are down, to also include the last flapped date.

    I was trying to use:
    show interfaces | except "Physical link is Up" | match "Last Flapped|Physical Interface"
    and 
    show interfaces extensive | match "Physical link is Down|flapped"

    However, neither of these give the desired output. It's almost like I need an "If" statement of some sort. 

    Any help is appreciated.

    Quick onbox op script if it's something that is useful often enough?...
    Take a look in sh-int-terse for a similar query, and the info that "show int media" is a good start to exclude logical (but I don't think you will get it straight out of the CLI)
    from jnpr.junos import Device
    from jnpr.junos.op.phyport import PhyPortTable
    
    with Device() as dev:
     phyports = PhyPortTable(dev).get()
     print ("|{:10}|{:4} | \"{:32}\"|{:32}|".format("Port", "Link", "Description", "Flapped"))
     for port in phyports:
      port.description = port.description or ""
      print ("|{:10}|{:4} | \"{:32}\"|{:32}|".format(port.name, port.oper, port.description, port.flapped))

    You can brute force it with bash from off-box too..

    ssh vmx01 "show int media ge-*" | egrep "(Phys|flapped)" | tr -d "\\n" | sed -e 's/Physical interface/\nPhysical interfaces/g' | grep "is Down"
    Physical interfaces: ge-0/0/2, Enabled, Physical link is Down  Last flapped   : 2022-12-07 11:29:16 UTC (5w1d 22:46 ago)
