ShoreTel Voice Switches IP Address from DHCP

ShoreTel 14 Maintenance Guide 65
IP Address from DHCP
The switch sends requests for an IP address to the DHCP server ten times at increasing intervals.
When the switch receives a response from the DHCP server, the boot process begins. If the switch
fails to get an IP address from the DHCP server, it uses the last assigned IP address. The switch
continues sending IP address requests to the DHCP server.
If the DHCP server sends a conflicting IP address while the switch is using an address from a previous
state, the entire system restarts. Use long lease times to prevent to prevent this. ShoreTel
recommends either static IP parameters or DHCP reservations.
If the switch does not receive an IP address from the DHCP server and an address is not available
from a previous state, the switch continues polling the DHCP server until it receives an address.
Setting the IP Address with VxWorks
®
If the switch or voicemail-enabled switch is not configured with an IP address and fails to boot from
flash, it cannot download the application and configuration from the FTP server. In this case, you can
manually set the IP address and boot parameters from VxWorks
®
accessible from the maintenance
port. Boot parameter changes do not take effect until the switch is rebooted.
