Managing Automatic Remote Configuration Download DHCP Client Auto-Configuration Process

OmniSwitch 6250/6450 Switch Management Guide May 2012 page 8-19

The detailed process of DHCP client auto-configuration on OmniSwitch is as follows:

1 At boot-up, the initial DHCP client starts with untagged VLAN 1.The DHCP client waits for 30

seconds for a DHCP lease.

2 If the lease is not obtained even after 30 seconds, the DHCP client is stopped on the untagged VLAN 1

and DHCP client is started on tagged VLAN 127. The DHCP client on tagged VLAN 127 waits for 30

seconds for a DHCP lease.

3 If the DHCP client does not get the lease in 30 seconds, DHCP client moves back to untagged VLAN 1

and this process continues until it gets the DHCP lease on any one of the two VLANs.

4 If a LLDP that is advertising the management VLAN ID is received on any of the switch ports, the

initial DHCP client on untagged VLAN and tagged VLAN 127 is stopped and a new DHCP client is

started on this tagged management VLAN.

5 Now, the DHCP Client created on tagged management VLAN waits infinitely to get a lease.

Note.

If the initial DHCP clients (untagged or VLAN 127) obtains an IP lease, the LLDP detection mechanism is

disabled to prevent the switch from starting a new DHCP client.

DHCP client is automatically stopped once a user logs in the switch through console port before getting

the DHCP lease. This condition applies for any type of DHCP client (untagged, tagged 127 or tagged with

LLDP associated management VLAN).

Once the DHCP client gets the lease, the Remote Config process does not stop even if the user logs on to

the switch through console port.
