i just purchased 2 2920's. they didnt have dhcp functionality until i updated them to the latest software rev. after doing so all seemed well. i created 2 dhcp pools and configured them for 2 vlans. these were working as intended while on my bench.
as these units will go offsite i wanted to do as close to a real test as i could. i took it to our core switch and plugged in directly with a /30 network connecting to vlan 690. only one untagged port is used for 690 (port 48).
that worked, all subnets were pingable etc. However, now the dhcp server stopped providing addressing for ANY dhcp pools. if i disable port 48, i get dhcp again. its repeatable.
i completely disabled and wiped the DHCP server and re-created it with the same results.
Any suggestions are appreciated.
