OmniSwitch 6600/7000/8800—Release 5.1.5.R04 page 77
PR 77401
On the OS7000, if the lease time expires for a particular IP address used by one switch, and the server is
out of new IP addresses, and another switch requests for a IP address, then the server gives out the IP
address whose lease has expired to this new switch. Thus resulting in duplicate IP addresses on the two
switches.
Workaround: Increase the lease time on the server or configure larger pool of addresses on the server.

In some cases, DHCP required packets with source IP address of 127.0.0.1 being received from the previ-
ous UDP relay hop.
Workaround: Configuring the correct IP interface would eliminate this problem.
PR 83528
Well known UDP ports are only configurable with a service name on an OS7000.

PR 83643
If a total of three non-BOOTP/DHCP Generic UDP relay services are configured on an OS7000/OS8800,
the last one configured will be replaced with a BOOTP/DHCP service the next time the switch reboots.
Workaround: Delete the BOOTP/DHCP service and enable the Generic service again.
PR 83947

Workaround: There is no known workaround at this time.
PR 84359
If a VLAN’s router IP address is changed on an OS7000, UDP relay agent still has the previous IP.
Workaround: Disable the relay service on the VLAN using the no ip udp relay service vlan, then enable
the relay service on the VLAN again using the ip udp relay service vlan command.
