Hi,

How to change ip address and default gateway of cisco nexus 1000v switch (VSM) ?

Hello DV,

To change the VSM's management ip address and gateway you must reconfigure the mgmt0 interface and appropriate ip route.

For example, you could do the following:

conf t

interface mgmt 0

ip address 192.168.0.100/24

exit

vrf context management

ip route 0.0.0.0/0 192.168.0.1

exit

copy run start

In the above situation I assigned 192.168.0.100 as the mgmt ip address of the VSM with gateway 192.168.0.1 and subnet mask corresponding to 255.255.255.0

PS: You may also pass the ip address command as the following if the length of the netmask is not known: ip address 192.168.0.100 255.255.255.0

Hope this helps.

Hi,

would changing the IP of the VSM have any impact on vCenter? Would there be any reconfig work required on the vCenter or the ESXi hosts?

Thanks

Hi Kassim,

No reconfiguration will be needed.

However, do note that if your VSM is connected to the VEM via L3, then changing the mgmt0 or control0 interface IP will require the modules to reconnect to the new ip on the interface.

Thanks,

kindly what is the diference between configuring the managment interface of the nexus switch with :

interface mgmt 0

ip address 192.168.0.100/24

and configuring it with the old way : 

interface vlan 1

ip address 192.168.0.100

[Tymofii Dmytrenko]

interface vlan - in band management

interface mgmt0 - out of band management

simple as that
