• Ingress bandwidth rate limiting on a per UNI port, per CVLAN, or CVLAN per UNI port
basis.
• CVLAN (inner) tag 802.1p-bit mapping to SVLAN (outer) tag 802.1p bit.
• CVLAN (inner) tag DSCP mapping to SVLAN (outer) tag 802.1p bit.
• Profiles for saving and applying traffic engineering parameter values.
Configuring VLAN Stacking in the Legacy mode consists of using a port or port-VLAN level approach
to tunneling customer traffic. Configuring VLAN Stacking in the Eservices mode consists of using an
approach based on defining an Ethernet service to tunnel customer traffic. Both modes are exclusive in
that the switch can only operate in one mode or the other. In addition, each mode has it’s own unique
CLI command syntax.
VRRPv2/VRRPv3
The Virtual Router Redundancy Protocol version 3 (VRRPv3) implementation is based on the latest
Internet-Draft for VRRP for IPv6. VRRP version 2 (VRRPv2) is based on RFC 2338.
Similar to VRRPv2, VRRPv3 is a standard router redundancy protocol that provides redundancy by
eliminating the single point of failure inherent in a default route environment. The VRRPv3 router,
which controls the IPv6 address associated with a virtual router is called the master router, and is
responsible for forwarding virtual router advertisements. If the master router becomes unavailable, the
highest priority backup router will transition to the master state.
Both versions of VRRP allow routers on a LAN to back up a static default route with a virtual router.
VRRP dynamically assigns responsibility for a virtual router to a physical router (VRRP router) on the
LAN. The virtual router is associated with an IP address (or set of IP addresses) on the LAN. A virtual
router master is elected to forward packets for the virtual router’s IP address. If the master router
becomes unavailable, the highest priority backup router will transition to the master state.
Authentication is not supported.
In addition, both versions support VRRP Tracking. A virtual router’s priority may be conditionally
modified to prevent another router from taking over as master. Tracking policies are used to
conditionally modify the priority setting whenever an ip interface, slot/port, and/or IP address
associated with a virtual router goes down.
VRRPv2 is available on all supported OmniSwitch platforms in this release.
Global VRRP Configuration
The following capabilities for VRRP2 were added:
• Globally enable or disable all or a range of VRRP instances.
• View or configure default values such as priority, preempt, or advertising interval on all or a
group or VRRP instances.
Web-Based Management (WebView)
The switch can be monitored and configured using WebView, Alcatel-Lucent’s web-based device
management tool. The WebView application is embedded in the switch and is accessible via the
following web browsers:
• IE6, IE7, Firefox 2, Firefox 3 for Windows NT, 2000, 2003, XP, Windows Vista
• Firefox 2.0 for Solaris SunOS 5.10
