new network address (since this function is beyond the scope of a VoIP gateway). Therefore,
administrators are advised to configure DHCP servers to allow renewal of IP addresses.
Note: If the gateway's network cable is disconnected and reconnected, a DHCP renewal is
performed (to verify that the gateway is still connected to the same network).
When DHCP is enabled, the gateway also includes its product name (e.g., ‘MP-118 FXS’ or ‘MP-
104 FXO’) in the DHCP ‘option 60’ Vendor Class Identifier. The DHCP server can use this
product name to assign an IP address accordingly.
Note: After power-up, the gateway performs two distinct DHCP sequences. Only in the second
sequence, DHCP ‘option 60’ is contained. If the gateway is reset from the Web/SNMP, only a
single DHCP sequence containing ‘option 60’ is sent.
If DHCP procedure is used, the new gateway IP address, allocated by the DHCP server, must be
detected.
Note: If, during operation, the IP address of the gateway is changed as a result of
a DHCP renewal, the gateway is automatically reset.
¾ To detect the gateway’s IP address, follow one of the procedures
below:
• Starting with Boot version 1.92, the gateway can use a host name in the DHCP request. The
host name is set to acl_nnnnn, where nnnnn stands for the gateway’s serial number (the
serial number is equal to the last 6 digits of the MAC address converted from Hex to
decimal). If the DHCP server registers this host name to a DNS server, the user can access
the gateway (through a Web browser) using a URL of http://acl_<serial number> (instead of
using the gateway’s IP address). For example, if the gateway’s MAC address is
00908f010280, the DNS name is acl_66176.
• After physically resetting the gateway its IP address is displayed in the ‘Client Info’ column in
the BootP/TFTP configuration utility (refer to Figure B-1 on page 259).
• Use the CLI (for detailed information on using the CLI, refer to Section
14 on page 223).
• Contact your System Administrator.
7.3 Using BootP
7.3.1 Upgrading the MediaPack
When upgrading the MediaPack (loading new software onto the gateway) using the BootP/TFTP
configuration utility:
• From version 4.4 to version 4.4 or to any higher version, the device retains its configuration
(ini file). However, the auxiliary files (CPT, logo, etc.) may be erased.
• From version 4.6 to version 4.6 or to any higher version, the device retains its configuration
(ini file) and auxiliary files (CPT, logo, etc.).
You can also use the Software Upgrade wizard, available through the Web Interface (refer to
Section
5.8.1 on page 155).
Note: To save the cmp file to non-volatile memory, use the -fb command line switches. If the file
is not saved, the gateway reverts to the old version of software after the next reset. For
information on using command line switches, refer to Section
B.11.6 on page 266.
