HSRP not working on NEXUS 5548

[Christian Balzereit]

Hey all,

got a little problem with hsrp on two cisco nexus.

Configuration should be correct, but the two nexus doesn't seem to 'comunicate'.

sh hsrp group 17

Vlan17 - Group 17 (HSRP-V1) (IPv4)

  Local state is Active, priority 110 (Cfged 110), may preempt

    Forwarding threshold(for vPC), lower: 1 upper: 110

  Hellotime 1 sec, holdtime 3 sec

  Next hello sent in 0.490000 sec(s)

  Virtual IP address is 172.16.17.1 (Cfged)

  Active router is local

  Standby router is unknown

  Authentication text "cisco"

  Virtual mac address is 0000.0c07.ac11 (Default MAC)

  2 state changes, last state change 1w3d

  IP redundancy name is hsrp-Vlan17-17 (default)

interface configuration (trunk cores)

interface port-channel1

  description Core-Channel

  switchport mode trunk

interface Ethernet1/1

  description Core-Channel

  switchport mode trunk

  channel-group 1 mode active

interface Ethernet1/2

  description Core-Channel

  switchport mode trunk

  channel-group 1 mode active

VLAN17 configuration NEXUS1

interface Vlan17

  no shutdown

  no ip redirects

  ip address 172.16.17.2/24

  hsrp 17

    preempt

    priority 110

    timers  1  3

    ip 172.16.17.1

  ip dhcp relay address 172.16.16.47

VLAN17 configuration NEXUS2

interface Vlan17

  no shutdown

  no ip redirects

  ip address 172.16.17.3/24

  hsrp 17

    preempt

    timers  1  3

    ip 172.16.17.1

  ip dhcp relay address 172.16.16.47

Thanks in advance for your help!

Looks like HSRP multicast is not making it across. Does Po1 connect the two Nexus 5548s? Are you able to ping physical IP address of other switch?

[Christian Balzereit]

Yeah sure:

Switch_2_new(SSI15430KTP)

                       Eth1/1        176    S I s     N5K-C5548P    Eth1/1

Switch_2_new(SSI15430KTP)

                       Eth1/2        176    S I s     N5K-C5548P    Eth1/2

ping 172.16.1.3

Btw: Multicast should work if CDP sees neighbours or am I wrong here?

Worked offline with Christian.. He has L3 modules offline due to missing license and he will try installing L3 base license and test.

Can you contact me about this issue.  I have two nexus 5548's that I thought both had layer 3 when they were purchase but when I do a show mod this is the output I get.
