I'm not sure if it's pertinent, but I noticed that the switch isn't getting ARP data for this vlan.
> show arp interface vlan.323 {master:0} > show interfaces vlan.323 Logical interface vlan.323 (Index 85) (SNMP ifIndex 619) Flags: Up SNMP-Traps 0x4000 Encapsulation: ENET2 Input packets : 0 Output packets: 50659 Protocol inet, MTU: 1500 Addresses, Flags: Is-Preferred Is-Primary Destination: 11.111.162.168/29, Local: 11.111.162.169, Broadcast: 11.111.162.175 {master:0}
EDIT: Rather than using the bootp helper, we also tried using the DHCP relay stanza. That didn't work either. We tested this on a different port, vlan and pxe device.
