■4876495: The port status is unstable
There is a known problem with Spanning Tree(STP and RSTP) when it is used
with aggregated links. When you have an aggregated link (a single link
comprised of multiple ports) between two switches and you enable spanning tree
on that aggregated link, the spanning tree control packets on the trunk link are
not reliably received by the switch in the chassis. The effect of this is that
spanning tree does not converge, the port state of the aggregate link keeps
changing, and network connectivity is likely to be disrupted. Firmware that fixes
this problemis now available from http://sunsolve.sun.com (patch number:
114783-xx).Until you have the fixed firmware installed, do not enable spanning
tree (either STP or RSTP) on any aggregated link.
■4804804: no switchport allowed vlan command fails
There is a known problem with the no switchport allowed vlan command
that enables you to remove all VLANs except the native VLAN from a particular
port. Issuing this command on a port that has learned a VLAN by using GVRP
causesthe learned VLAN to be assigned to the switch’s VLAN database as a static
VLAN instead of being removed from the database. If you need to remove static
VLANs from a port that has GVRP enabled, we recommend you use the no
switchport allowed vlan remove vlanid command (where vlanid is the
number identifying the static). If you do use the no switchport allowed
vlan command, you must delete manually from the VLAN database any
unrequired VLANs.
Todo this, type the following:
wherevlanid is the number identifying a VLAN that you want to remove from the
switch’s database. Firmware that fixes this problem is now available from
http://sunsolve.sun.com (patch number: 114783-xx).
■Sometimes error messages from the switch refer to ports by number instead of
name. The correct mapping of port names to port numbers is:
■The integrated switches on the Sun Fire B1600 blade system chassis are each
composed of two switch chips linked together.It is only possible to mirror the
trafficon one port by using another port that is on the same switch chip. And it is
only possible to enable flow control between two ports on the same switch chip.
