Features and Feature Enhancements in

ExtremeXOS 12.4.1

This section lists the features and feature enhancements supported in ExtremeXOS 12.4.1 software:

● Address Resolution Protocol (ARP) Payload Virtual MAC Learning by Bridge—This feature

provides the capability to learn MAC addresses that exist in the ARP payload.

● Bidirectional Forwarding Detection (BFD)—BFD allows you to register a discovered neighbor with

the BFD process and get the status of that neighbor. It also provides rapid failure detections and

informs of user of path convergence.

● Border Gateway Protocol (BGP) 4-Byte Autonomous System (AS) Number—This feature provides

the ability to configure 4-byte AS numbers for BGP, as well as the ability to peer simultaneously with

2-byte and 4-byte peers. This feature also introduces optional, transitive attributes AS4_PATH and

AS4_AGGREGATOR to propagate 4-byte AS path information across BGP speakers that do not

support 4-byte AS numbers.

● CLI Scripting Enhancements—The CLI scripting enhancements allow you to:

■ Nest script loading up to three levels

■ Exit from a script with an error code

■ Configure a script abort timer (time-out)

■ Manually set an SNMP trap using a CLI command

■ Configure time delay (TCL after function)

● Connectivity Fault Management (CFM) Support on a Service VLAN (SVLAN)—CFM support on a

SVLAN allows you to configure SVLAN ports to act as a maintenance end points (MEPs) and

maintenance intermediate points (MIPs).

● CFM Support on VPLS Node—This feature allows each VPLS node to be treated as a MIP in CFM.

VPLS-based MIPs process and respond to link trace messages (LTMs) and loopback messages (LBM).

● Digital Diagnostics Monitoring Interface (DDMI)—DDMI is an optional feature designed for

debugging optic modules. DDMI provides critical system information about Gigabit and 10 Gigabit
