z
For PPPoE, the AAL5 inPacket Discards counter might increment erroneously during
call setup when a packet is passed directly to PPPoE for negotiation rather than
being discarded. [Defect ID 51757]
Work-around
: Incremental InPacketDiscards during call setup do not necessarily
indicate a problem. However, we recommend you investigate an excessive count
because that might indicate a connection that cannot be successfully brought up for
some reason, such as RADIUS denials or improper configuration.
z
The inPacketOctetDiscards counter in the output of the
show atm vc atm
interface
vcd
command includes both inBytesDropped and inBytesUnknownProtocol
statistics. The inBytesUnknownProtocol statistics should be displayed by a separate
counter.
At the major interface level, the inPacketDiscards counter includes both
inPacketsDropped and inPacketUnknownProtocol statistics. The
inPacketUnknownProtocol statistics should be displayed by a separate counter.
[Defect ID 44286]
BFD
z
After you have shut down the interface to the next hop (for the route that is used to
establish the BFD session), output for the
show bfd session
command erroneously
indicates the shutdown interface as Management Interface (FastEthernet 6/0).
[Defect ID 174271]
CLI
z
When you issue a
run show ppp
command, the CLI changes the configuration level of
the command line to Global Configuration mode rather than remaining at the level
from which you issued the command. [Defect ID 52165]
Work-around
: Reissue the commands necessary to reenter the desired mode.
z
The logout subscribers all command may not log out all of the DHCP subscribers.
Although the bindings and DHCP addresses are cleared, the
show subscribers
summary
command may display some of the DHCP subscribers. [Defect ID 180176]
Work-around
: Try using the
dhcp delete-binding all
command. If this does not clear
the subscribers, you may want to reload the line module to avoid further issues.
DHCP
z
DHCP packets are not forwarded to the DHCP server over dynamically created
interfaces when all of the following are true: [Defect ID 180343]
−
DHCP relay or DHCP relay proxy is configured on the router.
−
The client-facing interfaces are created dynamically using bridged Ethernet over
static ATM PVCs.
−
The ip auto-detect ip-subscriber command is configured to enable packet
detection (packet triggering) and to trigger creation of dynamic subscriber
interfaces.
Work-around
: To avoid this defect, do all of the following:
−
Do not use the
ip auto-detect ip-subscriber
command to enable packet
triggering and to create dynamic subscriber interfaces
−
Ensure that DHCP external server is configured in the virtual router.
