ExtremeXOS 12.4.1 Release Notes
7
● Simple Network Management Protocol (SNMP) Support for IPv6—This feature adds the ability to
manage an IPv6 agent from an IPv6 SNMP manager. The agent supports IPv6 for communication of
SNMP management requests.
● Simple Network Time Protocol (SNTP) Client Support for IPv6—SNTP client support for IPv6
provides ExtremeXOS SNTP clients the ability to get the current time by querying an NTP server
running over IPv6.
● Spanning Tree Protocol (STP) Edge Safeguard Enhancements—This feature allows STP edge
safeguard to disable a port as soon as a bridge protocol data unit (BPDU) is received by allowing a
new CLI keyword
bpdu-restrict. It also provides a timer option to re-enable a disabled port.
● vMAN Terminology Change—The "vMAN" term is an Extreme Networks term that became familiar
to Extreme Networks customers before the Portable Bridge Notation (PBN) standard was complete.
The vMAN term is used in the ExtremeXOS software to support customers who are familiar with
this term. The PBN term is also used to establish the relationship between this industry standard
technology and the Extreme Networks vMAN feature.
● vMAN Enhancements—The feature enhancements allow you to configure tagged VLANs and
untagged vMANs on the same physical port. It also allows you to configure tagged VLANs and
tagged vMANs on the same physical port when the vMAN ethertype is not 0x8100.
● VPLS MIB Support—VPLS MIB support is now available for enabling SNMP to obtain information
about Layer 2 (L2) VPNs. These MIBs identify the pseudo-wires that are part of an L2 VPN. The
MIBs also enable the association of a pseudo-wire with its transport link state PDU (LSP). Extreme
proprietary MIBs allow you to identify primary and secondary LSPs in an RSVP LSP group. Support
has also been added for pseudo-wire up and down traps (SNMP notifications).
● VPLS With STP Redundancy—This feature provides a reliable method of directly connecting an
STP-protected VLAN to a VPLS network. Redundant VPLS nodes work with STP to handle topology
changes in a customer network, including informing other VPLS nodes when an FDB flush is
required. There is also no longer a CLI restriction preventing configuring a VPLS service on an STP-
protected VLAN.
● Virtual Router Redundancy Protocol (VRRP) Preempt Delay Option—VRRP preempt delay allows
a user to configure a delay time before preempting a lower priority master. Preempt delay is
configurable on a per VRRP instance. This option avoids black holing traffic when an active gateway
(for example, a router with a higher priority) recovers and preempts the backup router before the
active gateway is fully operational.
