IPmux-24 Ver. 1.5 Configuring IPmux-24 for Operation 4-19
All the keep-alive and ring status notifications are delivered using:
• Point-to-point (PtP) messages, sent between adjacent ring members.
• Multicast (Mcast) messages, sent to all ring members.
VLANs used for the ring status traffic (4001 and 4002 by default) must be unique
within the given network.
Before enabling ring protection, make sure that the following parameters have
been configured:
• Host IP address (see
Configuring IP Host Parameters )
• PW host IP address (see (
Configuring Bundle Connections )
• Bridge set to VLAN-aware mode (see
Configuring the Ethernet Bridge )
• All network ports set to be egress tagged ports in the ring VLAN (see
Configuring the VLAN Membership )
• Priority classification method is set to 802.1p (see
Configuring the Traffic
Priority
)
• Priority mapping (see
Configuring the Traffic Priority ):
 Priority 7 (reserved for the ring status traffic) mapped to traffic class 2
 Priority 6 (PW traffic) mapped to traffic class 1. The PW traffic priority
should be lower than the ring status traffic priority.
 Rest of the priorities mapped to traffic class 0.
³ To configure the ring protection:
• From the Protection menu (Configuration > System > Protection), configure
the necessary parameters and enable the ring redundancy (see
Figure 4-19
and
Table 4-2 ).
Chapter 5 details how to configure a typical ring protection application.
