It sometimes takes 6 or 7 minutes for the phones to load. This seems to occur only when the phone is unplugged and then plugged in again. I see the "getting ip" screen for about five minutes. I'm plugging the phone into a 4224 that is running dhcp. Is this simply an unfortunate quality of dhcp on the 4224, or something else? Has anyone else seen this? What up?
Here are some pertinent configs:
dhcp config:
ip dhcp excluded-address 192.168.2.1 192.168.2.2
ip dhcp excluded-address 192.168.0.1 192.168.0.10
!
ip dhcp pool pc
network 192.168.0.0 255.255.255.0
default-router 192.168.0.1
dns-server 24.25.195.1 24.25.195.3
!
ip dhcp pool phone
network 192.168.2.0 255.255.255.0
option 150 ip 192.168.0.2
default-router 192.168.2.1
dns-server 24.25.195.1 24.25.195.3
Eth switch ports the phones are plugging into:
interface FastEthernet5/1
no ip address
duplex auto
speed auto
switchport access vlan 3
switchport voice vlan 2
snmp trap link-status
!
interface FastEthernet5/2
no ip address
duplex auto
speed auto
switchport access vlan 3
switchport voice vlan 2
snmp trap link-status
VLANs that the phones and pcs are configured for:
interface Vlan 2
description vlan for the phones
ip address 192.168.2.1 255.255.255.0
h323-gateway voip bind srcaddr 192.168.2.1
!
interface Vlan 3
description vlan for the pcs
ip address 192.168.0.1 255.255.255.0

Use PortFast to decrease IP phone boot time

You may want to turn on port fast for ports where the phones are plugged in. This will keep the ports from participating in the stp learning, listening, blocking, etc. stage and go staight to forwarding. This make the phone boot up very fast. This is mention in the IP Telephony design guide as well.
