  • Cisco vs. Extreme Networks Switching Commands

    Don’t get your hopes up, I’m not taking sides here. I just wanted to show how the companies differ in basic switch configuration. Now for you who don’t know who Extreme is, they are the purple ones, better known as Extreme Networks. They offer some pretty nice products that compete very well with the likes of Cisco or HP. Feel free to check out their product line at http://www.extremenetworks.com/.

    Configuring VLANs:

    Extreme – Create 2 VLANs and basic configuration

    create vlan data
    configure vlan data tag 2
    configure vlan data ipaddress 10.0.2.1/24
    create vlan voice
    configure vlan voice tag 3
    configure vlan voice ipaddress 10.0.3.1/24
    enable ipforwarding

    Cisco – Create 2 VLAN interfaces and basic configuration

    vlan dat
    vlan 2 name data
    vlan 3 name voice
    exit
    configure terminal
    interface vlan 2
    ip address 10.0.2.1 255.255.255.0
    no shutdown
    interface vlan 3
    ip address 10.0.3.1 255.255.255.0

    Port Configuration

    Extreme

    -switch to pc on (vlan 2)
    configure vlan data add port 4 untagged
    -switch to phone (vlan 3) and PC (vlan 2)
    configure vlan voice add port 4 tagged
    configure vlan data add port 4 untagged
    -switch to phone (vlan 3)
    configure vlan voice add port 4 tagged
    -switch to switch
    configure vlan default add port 1 tagged
    configure vlan data add port 1 tagged
    configure vlan voice add port 1 tagged

    Cisco (skipping configure terminal)

    -switch to pc on (vlan 2)
    interface g0/4
    sw mode access
    sw acc vlan 2
    -switch to phone (vlan 3) and PC (vlan 2)
    interface g0/4
    switchport mode trunk
    switchport trunk encapsulation dot1q
    switchport access vlan 2
    -switch to phone (vlan 3)
    interface g0/4
    switchport mode trunk
    switchport trunk encapsulation dot1q
    -switch to switch
    interface g0/4
    switchport mode trunk
    switchport trunk encapsulation dot1q

  • Helpful Cisco Commands

    Well, this is my first tech post so I’ll make it an easy one. I’ll put a few of the commands that I regularly utilize on Cisco routers and Switches to make my life easier.

    | (Pipe) command output modifier –

    Alrighty, this truly is a basic command. You issue a normal command at the privilege exec level and add the | (pipe) afterwards followed by an i (include) e (exclude) or b (begin). Begin is not available in all IOS versions.

    Command Example:

    show run | i ip route

    would show something like this:

    ip route 10.0.0.0 255.255.255.0 11.24.1.1 name default
    ip route 10.1.255.0 255.255.255.0 11.24.1.2 name backup_net

    If you were to replace the i with a b the output would begin at “ip route” and continue on with the rest of the config. This would be useful for those really long configs where you might be working on the dial-peers and don’t care to scroll through 500 lines of the config to get there. The e option would exclude anything that you have following it. This might come into handy when you want to skip ip address or access-lists. Hope this helps, I was lucky enough to learn these tricks early on and didn’t have to struggle for too aweful long. Good luck.
