Avaya X330WAN User’s Guide 61
Note: Some LAN data applications do not support fragmented packets. In this case,
do not change the MTU from its default of 1500.
X330WAN-2USP-1(super-if:Serial1)# bandwidth 128
• VoIP configuration:
X330WAN-2USP-1(super-if:Serial1)# voip-queue
X330WAN-2USP-1(super-if:Serial1)# ip rtp header-compression
X330WAN-2USP-1(super-if:Serial1)# ip rtp compression-connections 20
(4)
X330WAN-2USP-1(super-if:Serial1)# ip rtp port-range 2048 3028
(5)
X330WAN- 2USP-1(super-if:Serial1:1)# queue-limit 1 12
(6)
X330WAN-2USP-1(super-if:Serial1)# exit
• Static routes configuration:
X330WAN-2USP-1(super)# ip default-gateway 2.2.2.2
X330WAN-2USP-1(super)# ip route 3.3.3.0 24 serial 1
X330WAN-2USP-1(super)# ip route 33.33.33.0 24 serial 1
* Description of footnoted commands (also applies to identical stages in configuring
Site B):
(1) At this stage you apply Priority 7 to Voice Control traffic.
(2) At this stage you apply Priority 6 to RTP traffic.
(3) At this stage you apply maximum trust between 802.1p priority and DSCP.
(4) At this stage the number of connections (20) depends on the number of phones.
(5) At this stage you are matching the RTP port range to that of the G700.
(6) At this stage the default queue size is 6, and since cRTP is enabled you can
double the VoIP queue size.
Configuration Example for Site B
The following is the configuration procedure for the X330WAN-2DS1, as shown in
Figure 4.10:
• Loopback and PMI interfaces configuration:
X330WAN-2DS1-1(super)# interface Loopback 1
X330WAN-2DS1-1(super-if:Loopback1)# ip address 20.20.20.20 32
The Primary management interface has changed. Please copy the running
configuration to the start-up configuration file, and reset the
device.
X330WAN-2DS1-1(super-if:Loopback1)# exit
X330WAN-2DS1-1(super)# copy running-config startup-config
X330WAN-2DS1-1(super)# reset
