Q01939345
The Device Manager does not display the status of all power supplies with
the front panel LEDs. You can see the status of the Power supply under
Edit, Chassis, Power Supply.
Q01945335
On an Ethernet Routing Switch 56xx unit, port mirroring mode XrxYtx does
not mirror broadcast, multicast and unknown unicast if the X and Y mirrored
ports are in different MLTs.
Q01948343
In some situations on a pure 56xx stack (mirrored ports are not on the
same unit in the stack or traffic enters one unit and exits another one from
the stack), port mirroring modes XrxYtx, XrxYtxOrYrxXtx, XrxOrYtx and
MAC-based mirroring modes may multiply the unicast traffic that exits the
stack. The problem is not present if multicast or broadcast traffic is mirrored.
The problem is not present in port mirroring modes XrxYtx, XrxYtxOrYrxXtx,
or XrxOrYtx if the monitor port is placed on base unit.
Q01950311
If you enable ARP-inspection on NSNA or ADAC Voice VLAN, the IP-phones
only work properly on the base unit.
Q01950071
If you disable VLACP on an Ethernet Routing Switch 5698 unit before you
start the unit, you cannot enable the unit with the
vlacp enable
command
in Global Configuration mode. Workaround: Disable, then enable VLACP
on the unit.
Q01954180
You cannot disable the AlwaysBroadcast parameter on a VLAN when you
toggle off from Device Manager or set the value from the MIB Browser tool.
Q01953968
In a standalone ERS5632FD unit or stack that contains an ERS5632FD
unit, if the system uses 10 G ports in an MLT configuration, do not enable
DHCP snooping globally. If you enable DHCP globally, it could cause the
unit to restart.
If you use this configuration, upgrade the stack to the maintenance software
release 6.0.1 from the Technical Support site at
as described
in the Release Notes. With release 6.0.1, you can enable DHCP snooping.
Q01914709
When you download the ACG file with default settings from a SSH session,
the ssh commands will fail (this is because SSH is already enabled on that
unit).
Q01947854
When a PIM interface comes up, it identifies as a DR. Then DR election on
that multi-access link happens after exchange of hello messages. If for some
reason DR is flapped, by the time DR is down, the non-DR becomes the DR
and therefore it installs (*,G) and (S,G) for a particular steam. When the
original DR comes back again, the re-election of DR happens with exchange
of hello messages.
In this time frame (Before DR re-election is completed), if the IGMP reports
and multicast traffic are sent on the multi-access link, then both non-DR and
DR PIM routers may install the (*,G) & (S,G) entry as DR. This is an assert
condition. The assert mechanism in this scenario may not work and may lead
to duplicate packets as both DR and non-DR will have (S,G) for the same
stream for a single multi-access link.
