Table 21: Configuring network connectivity
Field Name Setting
MTU Sets the maximum size of each IP packet the XT Codec Unit can
send to the network.
If the system or the remote endpoint transmits IP packets larger
than the configured MTU size, they are dropped or fragmented. To
avoid packet loss or fragmentation, decrease MTU. If packets are
smaller than the configured MTU size, increase MTU.
The maximum and minimum values you enter in this field depend
on the mode selected for placing calls: IPv4 or IPv6. (These are
configured in Configuring IP Addresses on page 77. Both for IPv4
and IPv6 MTU size is set by default to 1360 octets. You can set the
MTU size to these ranges:
•
The minimum allowed value for IPv4 is 576 octets.
•
The minimum allowed value or IPv6 is 1280 octets.
•
The maximum allowed value for both is 1500 octets.
Speed/Duplex mode Set the speed and transition mode as follows:
•
Automatic: The XT Codec Unit selects the Ethernet speed
and transmission mode. We recommend this default mode.
•
Auto - up to 100/Full, Auto - up to 100/Half, Auto - up to
10/Full, Auto - up to 10/Half: If necessary for your network
requirements, select one of these semi-automatic modes. The
XT Codec Unit selects the Ethernet speed and transmission
mode according to the specified values.
•
Manual: You must configure speed and transmission mode
and know the network and remote endpoints requirements.
Speed Select the suitable Ethernet speed: 10, 100, or 1000 MBPs for
GLAN.
This field is read-only if you selected Automatic for Speed/Duplex
mode.
Duplex mode Select the data transmission mode that is defined for your network
router or switch, either duplex or half-duplex mode.
This field is read-only if you selected Automatic for Speed/Duplex
mode.
