Clarifications and Known Behaviors
ExtremeWare 7.4.3 Installation and Release Notes 67
Extreme Real Time Statistics Does Not Work When There are 24+ Ports
When Network Management tool EPICenter tries to get real time statistics on an Extreme device that
has more than 24 ports, it sometimes fails (PD3-14524212, PD3-15975950).
Stacking
Bootup Time
A full stack consisting of 8 Summit 200 or Summit 300-24 switches amy take slightly over two minutes
to bootup. However, a full stack of Summit 400 switches would take just under two minutes on the
average to bootup.
Traffic Grouping Based on Access Lists, DSCP Across Units Not Working Properly
Traffic grouping based on access-lists across units on a Summit 200-48, or across slots in a stack of
Summit 200 series switches is not supported (PD3-35723040).
Task Utilization is High During a CPU DoS Attack
When CPU-DoS protection is enabled in Stacking mode and a Dos attack is attempted on the switch
high task utilization is observed (PD3-27794280).
Configuring the Mirrored-to Port
Once you configure the mirrored-to port to be either tagged or untagged, if you change it from tagged
to untagged, or from untagged to tagged, the change will only take affect after a reboot (PD3-29054741).
VLAN Tagged 2 Cannot be Used When Stacking is Enabled
If stacking is enabled on the switch, the switch will not allow you to create a user VLAN with a tag of 2
(PD3-30253861).
CLI Commands Executed from Pseudo TTY Sessions
Running CLI commands executed from pseudo-TTY sessions results in excessive and incomplete output
(PD3-23616276, PD3-25226542).
Moving from a Stack Image to a Non-stack Image
When moving from a stack image to a non-stack image, run the disable stacking command or chose
the
nonstack conf option (PD3-29013801).
Wrong Number of Ports Displayed in Default VLAN
The default VLAN shows the incorrect number of active ports after all ports are deleted from the VLAN
if the following procedure is followed:
1 Save the configuration using the ExtremeWare 7.4 image.
2 Reboot the switch and save the configuration using the ExtremeWare 7.3 image.
3 Reboot the switch to the ExtremeWare 7.4 image using the saved ExtremeWare 7.3 configuration.
