Problem Reports
PR 53663
MAC load balancing does not spread out the MACs among 4 ports on the OS7000.
Workaround: There is no known workaround at this time.
PR 54930
The CLI command show mac-address-table count does not have an equivalent in SNMP or WebView on
the OS7000.
Workaround: There is no known workaround at this time.
PR 57013
Boot.cfg only changes the age-time value for VLAN1 on the OS7000 although its been configured for all
the VLANs.
Workaround: The user should specify the VLAN information while configuring aging time for MAC
address table in the boot.cfg, like: mac-address-table aging-time 1000000 VLAN 2.
PR 57976
All MACs age out when a cable is pulled and re-inserted after traffic is stopped during Source Learning on
the OS7000. Spanning Tree recalculates and flashes all MACs belonging to the same VLAN as the cable
is re-inserted.
Workaround: Make the port being unplugged an "edge port". Spanning tree will ignore the re-insertion
event and not flash out all MACs learned.
PR 59745
Due to the time required for the aging check, the aging-time is not very accurate for small measures of
time i.e. under 1 minute on the OS7000.
Workaround: There is no known workaround at this time.
