I just got done setting VLAN 1 to untagged on port 1 literally 8 minutes before you posted this, and everything started working no problem -- VLANs communicating, DHCP working for both VLANs, etc. BTW, for anyone else running into this problem later on: on the 62xx series switches, General = Trunk on the 3xxx/5xxx series switches. Also, do NOT tag VLAN 1 on the General ports... Thanks for all your help, bh!
Hello -- I'm editing this to be more direct in hopes that someone will be able to help and save me a call to tech support. My scenario is this: I started a new job at the beginning of this year, and we're running out of IP addresses on my Class C /24 network, and would prefer not to have to reconfigure the entire network's subnet mask, and really don't want to change IPs of the servers. My colleague suggested VLANs, but neither of us have set them up before -- guess who gets to get it working. :) What I've got so far: I have 3 VLANs set up, 1,5, and 10. One is the default, 5 is newly created for management (may be changed to some obscure number - 1337 or something), and 10 is the new OfficeDHCP VLAN. Servers, Printers, and all other static IP addresses (shop PCs, one department's Macs, scanners, and several machines that have static IPs that we can not change without calling in the service company) will remain on VLAN 1. The aptly named VLAN 10 will be the new OfficeDHCP vlan. My test bed is a 6248 (which will be the live switch when this is all working), and a 6024 (which is emulating 5224s in the live environment). I have devices on both the 6248 and the 6024 on VLAN 10 that are talking no problem. I can NOT, however, get a device on VLAN 1 to talk a device on VLAN 10, even if both are on the same switch (the 6248). Below is 'sh running config,' 'sh ip route,'  and  'sh ip int' of the 6248: -------------------------------------console#show run!Current Configuration:!System Description "Powerconnect 6248, 3.2.0.7, VxWorks 6.5"!System Software Version 3.2.0.7!Cut-through mode is configured as disabled!configurevlan databasevlan 5,10vlan routing 1 1vlan routing 10 2exitstackmember 1 2exitip address 192.168.5.10 255.255.255.0ip address vlan 5ip routingip route 192.168.10.0 255.255.255.0 192.168.10.1interface vlan 1routingip address 192.168.0.80 255.255.255.0bandwidth 10000ip mtu 1500exitinterface vlan 5name "DeviceManagementVLAN"exitinterface vlan 10name "OfficeDHCP"routingip address 192.168.10.2 255.255.255.0exitusername "admin" password 'asdfasdfasdf' level 15 encryptedno spanning-treedhcp l2relaydhcp l2relay vlan 1,10!interface ethernet 1/g1spanning-tree disableswitchport mode generalswitchport general allowed vlan add 10 taggedswitchport general allowed vlan add 1 taggedexit!interface ethernet 1/g41switchport access vlan 10exit!interface ethernet 1/g42dhcp l2relaydescription 'Trunk Port for Test VLAN'switchport mode generalswitchport general allowed vlan add 5,10 taggedswitchport general allowed vlan add 1 taggedexit!interface port-channel 1spanning-tree disableexitsnmp-server community public rw ipaddress 192.168.5.10exitconsole#-------------------------------------console#show ip routeRoute Codes: R - RIP Derived, O - OSPF Derived, C - Connected, S - Static       B - BGP Derived, IA - OSPF Inter Area       E1 - OSPF External Type 1, E2 - OSPF External Type 2       N1 - OSPF NSSA External Type 1, N2 - OSPF NSSA External Type 2C      192.168.0.0/24 [0/1] directly connected,   vlan 1C      192.168.10.0/24 [0/1] directly connected,   vlan 10console#-------------------------------------console#show ip intManagement Interface:IP Address..................................... 192.168.5.10Subnet Mask.................................... 255.255.255.0Default Gateway................................ 0.0.0.0Burned In MAC Address.......................... 5C26.0A91.C3CFNetwork Configuration Protocol Current.........
