68 ExtremeWare 7.4.3 Installation and Release Notes
Clarifications, Known Behaviors, and Resolved Issues
4 If all ports are deleted from the default VLAN, the incorrect number of active ports is shown.
(PD3-28261405)
Frames Being Received After Setting MAC Limit to Zero for Port
In a stack of two Summit switches, create a VLAN and add some ports. Set the MAC limit to zero on
one of the ports. If you send frames from that port to the other port, the receiving port should receive
one frame when in fact it is receiving multiple frames (PD3-25226331).
Able to Receive Frames Even After Port is Locked for Learning
After creating a VLAN and adding ports from the master and backup switches, once you lock MAC
address learning, all frames should be discarded but some multiple frames, not all, are received
(PD3-24903111).
Ninth Switch Introduced in a Stack Does Not Become the Stand-alone Master
When connecting a switch to a stack of eight switches through the stack port and enabling stacking in
the added switch, the added switch, or ninth switch, stays in the "Discovery State" and does not become
a stand-alone master (PD3-24239271, PD3-24272096, and PD3-24272111).
bcmRX Drops Messages When Adding or Deleting a VLAN with Traffic
When adding or deleting a VLAN with traffic on a stacking DUT, the console is flooded with the
following error message:
[bcmRx] ATP RX Dropping non-ready rx trans...
(PD3-26514621)
Stacking Supports Up to a Maximum of 8 Switches
In ExtremeWare 7.4, the current stacking implementation supports up to a maximum of 8 switches in a
stack. However, under certain configuration scenarios, the maximum number supported per switch may
be less than 8. Refer to the ExtremeWare 7.4 User Guide for more information (PD3-26601290).
Mix Mode Stacking is not Supported
Mixed mode stacking, that is, stacking between Summit 200/300/400 series switches, is not supported
in this release (PD3-25989591).
Downloading a Configuration to a Stack
After downloading a configuration to a stack, all slots must be operational before attempting to save the
configuration (PD3-27126942).
