Errors and Omissions

Data is invalid

error with no explanation. The

new firmware returns an error describing the field
containing the error and then returns to the page
allowing the error to be corrected.

Command Line Interface

The output of the

bridge port summary

CLI

command has been improved:

■

The

stpState

field has been replaced by

Link

and

Spanning Tree

columns to more accurately

report the active port status.

■

The

fwdTransitions

field has been renamed

Forward Trans

■

The

LACP PartnerID

field now reports

LACP disabled

if the protocol is disabled or not

supported on the port.

The output of the

bridge port detail

CLI

command has been improved:

■

The

stpState

field has been added. This shows if

the Spanning Tree Protocol (STP) has been enabled
on the port. The field will read

Enabled

if STP is

enabled on the port, even if STP is disabled globally
on the unit.

■

The currently active spanning tree state for the
port is reported in the

Spanning Tree

column

of the VLAN table. Please note that the product
supports a single spanning tree state for all VLANs
as per the

802.1d Spanning Tree

specification. It

does not support

802.1s Spanning Tree per VLAN

■

The

LACP PartnerID

field now reports

LACP disabled

if the protocol is disabled or not

supported on the port.

Traffic Prioritization

In previous versions of the software, the DSCP
prioritization of the

CS6

code point defaulted to

802.1d priority 7. This has been corrected. The

CS6

code point now defaults to 802.1d priority 6.

VLANs

In previous versions of the software, removing a port
from a VLAN left static entries bound to the
port-VLAN. This has been fixed. When you remove a
port from a VLAN all static entries for that port-VLAN
will be deleted.

802.1x Network login authentication:

■

In previous versions of the software, authentication
attempts for valid users would occasionally fail.
The bug causing this has been fixed.

■

The user name reported in the CLI command

security network access detail

was

occasionally displayed with incorrect trailing
characters. This has been fixed. The user names are
now displayed correctly.
