ExtremeXOS 12.4.4 Release Notes
8
- 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)—Provides ability to
configure SVLAN ports to act as a maintenance end points (MEPs) and maintenance intermediate
points (MIPs).
● CFM Support on VPLS Node—Allows each VPLS node to be treated as an MIP in CFM. Also
enables VPLS-based MIPs to process and respond to link trace messages (LTMs) and loopback
messages (LBM).
● Digital Diagnostics Monitoring Interface (DDMI)—Optional feature designed for debugging optic
modules. DDMI provides critical system information about Gigabit and 10 Gigabit optical
transceiver modules. Not all transceivers support DDMI capability. In ExtremeXOS 12.4.1, DDMI is
supported only on XFPs.
● Domain Name Service (DNS) Client Support for IPv6—Provides ExtremeXOS applications the
ability to convert hostnames to IP addresses by querying an external DNS server.
● Equal Cost Multi-path (ECMP) Scaling— Increases the number of IPv4 longest prefix match (LPM)
routes that can use equal cost multi-path (ECMP) by sharing common ECMP gateway "sets" in
hardware. ECMP scaling is supported on the following platforms: BlackDiamond 8000 a- and e-series
modules, BlackDiamond 8800 c-series modules, BlackDiamond 8900 modules, BlackDiamond 20800
modules, and Summit X250e, X450a, X450e, X480, and X650 switches.
● Extreme Loop Recovery Protocol (ELRP) Port Shutdown—Provides ability to monitor individual
VLANs for loops. In addition to log and trap notifications, this feature provides the option to disable
a port on loop detection.
● Hitless Failover with Nettools—Provides a moderate level of hitless failover by protecting a switch
from rebooting when the Nettools process fails.
● Identity Management—Allows you to track users or devices that access a network based on device
name or user name (that is, user identity). User identity is captured based on network login
authentication, Link Layer Discovery Protocol (LLDP) discovery, and Kerberos snooping. The user or
device identity is mapped to its associated IP address, MAC address, computer hostname, domain
name, VLAN, and switch port location. This information can also be sent to EPICenter for
centralized reporting.
● IPv6 Routes with Masks Greater than 64 Bits—BlackDiamond 8900 modules and Summit X650 and
X480 switches support hardware forwarding for IPv6 routes by using dedicated hardware.
BlackDiamond 8000 a- and e-series modules, BlackDiamond 8800 c-series modules, and
Summit X250e, X450a, and X450e switches also support hardware forwarding for up to 256 routes
with masks greater than 64 bits by sharing the hardware used for ACL support.
● Medium-Specific Configuration CLI—Medium-specific configurations on combo ports allows users
to select the medium (fiber or copper) they want to configure. Configuration for each medium is
stored separately and simultaneously. This feature is only supported on Summit platforms having
combo ports.
● MIB Support for Connectivity Fault Management (CFM)—Provides read access for CFM MIB
objects via SNMP.
● Multicast Debug Tools—The multicast trouble-shooting commands, mrinfo and mtrace, are now
included in the implementation of IP multicast. Mtrace is the multicast equivalent of the unicast
"trace route" mechanism and is an effective debug command for testing multicast reachability. The
multicast router information tool, mrinfo, requests information from a router.
