I have a 6509 switch that has a .1q trunk to a 2960G command switch with 2 members. I replaced an unmanaged hub with a new 2960 (non-G) and established a trunk back thru the 2960G ultimately to the 6509. The issue is: I can statically assign the switchport to any other VLAN EXCEPT the VLAN it needs to be onâ¦VLAN 240. The symptoms are more specifically
: Working scenario ( VLAN 210 )
-DHCP client obtains IP address within 3 seconds
-I am able to ping DHCP server on different subnet
:Non-working scenario (VLAN 240)
-DHCP client obtains IP address after >31 seconds (usually get a timeout error on the renew, but then gets and IP in a couple of seconds)
-IPCONFIG /ALL reveals that current lease time and correct DHCP options
-UNABLE to ping default gateway
-arp -a reveals an invalid MAC
Odd thing about this is that the command switch contains primarily VLAN 240 ports. All of the current members of VLAN 240 work fine. When I went to the command switch and enabled 1 more port for 240, I encountered the same problem.
There are no access-lists to prevent this traffic
Any assistance is greatly appreciated.
