I have Soundstation IP 6000s UCS 4.0.10.0568 and am trying to use Custom option code 192 to provide a list of 5 VLAN IDs.
VLAN-A=0811+0812+0813+0814+0815;
The phone appears to come up reletively quickly if the available VLAN is the first in the list (811). However, if the valid VLAN is 2nd (VLAN) it takes about 2 minutes and 30 seconds to get an IP on that VLAN. And it seems like I have to adde 2 1/2 minutes for each VLAN after that.
I have the following VLAN settings on the phone:
VLAN Filtering = Enabled
LLDP = Disabled
CDP = Disabled
DHCP VLAN Discovery = Custom
DHCP VLAN Option = 192
My switch ports are all configured with the default VLAN 1 untagged and VoIP VLAN 8xx Tagged.
Is there any way to speed up the DHCP Release and Request process?
