Mediatrix 4100
The following is the corresponding DHCP setup, assuming the Management server is located at 10.3.2.201
and the Syslog server is located at 10.3.2.200 (port 1024):
Option 43 (vendor specific option) contains the hexadecimal sequence
0xC80x40xA0x30x20xC9 inserted among other sequences.
Option 250 (site specific option) contains the hexadecimal sequence 0xA0x30x20xC80x400.
Error Handling
In the event of a network or server failure, this section describes the application behaviour and/or replacement
values to use.
DHCP Server Failures
If the Mediatrix 4100 cannot contact the DHCP server, it performs one of the following actions:
1. Retries contacting the DHCP server until it answers. The Mediatrix 4100 does not restart.
2. Uses the replacement value from Table 45
for all variables that depend on the DHCP.
This assumes that the Mediatrix 4100 is set to get its IP information via a DHCP server.
Vendor/Site Specific Option Missing
If a vendor specific or site specific option is missing from the DHCP server answer, the Mediatrix 4100 uses
the replacement value from Table 45 for each variable that depends on missing vendor/site specific options.
DNS Failures
If the DNS cannot be contacted, the Mediatrix 4100 performs the following steps:
1. The Mediatrix 4100 sends a first request to the primary DNS server.
