New Features in ExtremeWare 6.2

Additionally, a load-shared group of ethernet ports can be backed up with a set of load shared
redundant ethernet ports. Should a link go down in the active load shared group, the entire group
will fail over to the redundant group.
The commands for configuring this feature are described in detail in Chapter 4, “Configuring Slots
and Ports on the Switch” in the ExtremeWare Software Command Reference Guide
• BGP Enhancements: A number of enhancements were made to BGP support. They include the
following:
— Support for displaying the BGP community in either decimal number format or
<AS number>:<community number> format. This applies to both “show configuration” output
and in configuration upload files. One or the other can be specified, they cannot be mixed.
— Support for adding or deleting a particular value to the MED attribute in the BGP Route that has
been received, and support for removing the MED attribute completely. During the addition, if
the sum of the incoming MED and the value that is being added exceeds the maximum allowable
value of the MED, then the value is set to the allowable maximum. During the deletion, if the
incoming MED value is less that the value that is being deleted, then the MED is set to zero.
— The route map has been enhanced in 6.2 to support arithmetic determination of a MED value
from IGP metric to route’s NextHop — it derives a MED value from the local AS’s topology for
outbound BGP routes to an EBGP neighbor.
— The ability to remove these Private AS numbers (AS numbers in the range 64512-65535) from the
AS Path attribute associated with the routes in the updates sent to EBGP neighbors.
These enhancements are described in Chapter of the ExtremeWare Software User Guide. Related
commands are described in detail in Chapter 18 of the ExtremeWare Command Reference Guide.
Features Added or Enhanced in v6.2.1
• Odometer: An Odometer feature has been added to keep track of how long each individual
component in the whole switch has been functioning since it is manufactured. This odometer
counter will be kept in the EEPROM of each monitored component. This means that even when the
component is plugged into different chassis, the odometer counter will be available in the new
switch chassis. The following components are monitored by the odometer:
— For the Black Diamond — MSMs and I/O cards
— For the Alpine — SMM, I/O slots, and power supplies
— For stackable switches — the CPU
The odometer “readings” have been added to the output from the
show switch command.
• WCR Modifications: Changes have been made to the existing WCR feature to support the option of
specifying the L4 source IP port in place of the L4 destination IP port. The change is to basically
support the requirements of a Summit Px1 application switch when deployed in a half-NAT mode.
This requires the ability to redirect the traffic stream returning from the proxy server up to the
Summit Px1 switch. The most direct way of identifying these traffic streams is by the L4 source port.
The WCR feature was also enhanced to load balance among the next hops based on the IP source
addresses of the flow redirect rule.
In addition, configurable health checks support has been added to control the frequencies.
• BGP enhancements: BGP update message transmission has been optimized for faster synchronization
and convergence. Now the transmission of all the Internet routes should take approximately 30
seconds.
