  1. hi Rene
    at the beginning of the lab, i wasn’t able to issue the following commands

    SwitchA(config)#interface fa0/17
    SwitchA(config-if)#standby 1 ip 192.168.1.3
    

    the thing is SwitchA does not have the option standby under interface, not unless i convert this interface as a layer 3 int with command “no switchport”, then it has the option, but when i try to type the following command

    standby 1 ip 192.168.1.3

    then it give me the error that overlaps with vlan 1, and this is because the layer 3 interface does not belong to any vlan, can you please advice.

    or should i

  2. Hi Rene i lab this on a real cisco equipments and the lab was awesome thank you very much. Please can you make a video training on how to setup a complete ACS server and snmp configuration for a newly cisco switch/router. Moreover, we will like to see more of a recommended way of designing and implementing cisco configuration a network thank you.

  3. Rene,
    Hi. Couple questions/validations when you have time.

    1. I know it is best practice to have the HSRP hold timer be at least 3x’s the hello, but I did some lab testing and it appeared to work ok for instance with the hold time 2x’s the hello. Is this expected - is the idea just to have the hold time be large enough to not cause an unnecessary transition and that is what Cisco found to be best practice?
    2. What are the benefits of HSRP v2 over v1 - is it just the increased number of HSRP group numbers supported?
    3. If I have more than two routers that are part of th

  4. Shree,
    This depends on which HSRP is being used, version 1 or version 2.

    For version 1, the gateway’s MAC would appear to be: 00:00:0c:07:ac:XX (where XX is the HSRP group number you have configured).

    For version 2, the gateway’s MAC would appear to be: 00:00:0c:9f:fX:XX (again, where X is the configured HSRP group)

  5. Hello Florian!

    Let’s begin with Cisco’s explanation and we’ll go from there. Cisco says that this command:

    Sets the priority level used to select the active router in an HSRP group. The level range is from 0 to 255. The default is 100. Optionally, sets the upper and lower threshold values used by vPC to determine when to fail over to the vPC trunk. The lower-value range is from 1 to 255. The default is 1. The upper-value range is from 1 to 255. The default is 255.
