Is it possible to use in band management (not using the dedicated nic) and have it be setup for DHCP?

If so how do I set that up on an ex3400?

You just assign a vlan for management, give it a layer3 interface at have it receive it's IP via dhcp.

Example:

user@EX3400-VC# show vlans
mgmt {
    vlan-id 10;
    l3-interface irb.10;
}

user@EX3400-VC# show interfaces irb.10
family inet {
    dhcp;
}

As I am trying to make this as simple as possible. Is it also possible to make the mgmt vlan the default vlan for all ports? As in all ports are on VLAN 1 and it is also the mgmt VLAN?

Hi Matt,

Just a quickie for you.

I know you want to make it as simple as possible, but from a security perspective, VLAN 1 should always be disabled and a different VLAN configured.

The reason: As you have just stated, all ports are on VLAN 1. Most switches straight from the box are VLAN 1 by default.

As for the the DHCP issue, just complete what has already been mentioned.

I understand the VLAN 1 issue. This is just a lab switch. Thank you for your help.

one more question. Once the switch pulls an IP. Is there a command to show what IP it pulled?

show interface terse irb

Will show the active ip address on the interface.
