Chapter 1 Getting to Know Your MSC
Management Switch Card User’s Guide
53
You can configure DSCP-to-IEEE 802.1p mappings to allow the MSC to prioritize all incoming traffic
based on the DSCP value according to the mapping table.
System Monitoring
• System status (link status, rates, statistics counters)
• Temperatures, voltage reports and alarms.
Bandwidth Control
The MSC supports rate limiting in 1 Mbps increments on the individual Gigabit Ethernet interfaces
allowing you to limit backbone bandwidth usage. You can also apply bandwidth control on multicast
traffic.
IP-aware Bridging
The line cards can forward frames based on the destination IP address, instead of the destination
MAC address, and replace the source MAC address with its own MAC address. This provides better
scalability and security for large-scale access networks, especially with Ethernet.
Single End Loop Test (SELT)
This feature checks the distance to an ADSL subscriber’s location.
Dual End Loop Test (DELT)
This feature (also called a Loop Diagnostic Mode test or LDM test) provides details about the
condition of an ADSL subscriber’s line.
