KNOWN RESTRICTIONS AND LIMITATIONS
10/24/01 P/N: 9038090-17 CUSTOMER RELEASE NOTES Page: 22 of 34
F0615-F Subject to Change Without Notice
Hot-Swap I.D.
Point-to-Point Protocol (PPP) does not renegotiate when a POS card (with Automatic Protection
Switch enabled) is hot-swapped, or if either end of a connection goes down. A system reboot is
required at both ends in order for PPP to renegotiate.
08223
Interface I.D.
If an IP and IPX interface are created for a VLAN, and the IP interface is removed, traffic may stop
on both the IP and the IPX interface.
Workaround: Comment-out the IPX interface, and then comment it back in.
F1421
Internet Control Message Protocol (ICMP) I.D.
Ping packets sent by the X-Pedition have the default Type of Service (ToS) field assigned to 0xFF,
which does not conform to current RFCs.
Workaround: This value may be changed with the ping command parameter tos.
F0662
If the X-Pedition receives a packet larger than the receiving port's MTU size, and it cannot fragment
that packet, the packet will be dropped. If the packet was to be routed, the X-Pedition will reply with
an ICMP error message; however, if the packet was to be bridged then no message will be sent.
Workaround: Configure the X-Pedition to route only ICMP packets.
F1268
Internet Protocol (IP) I.D.
Entering a static route with a 32-bit netmask and the same destination and preference as an existing
host route (and vice-versa) will cause GateD to stop functioning.
F1399
Layer-2 I.D.
The maximum available number of static-entry filters is 505. F0731
Layer-3 I.D.
The X-Pedition may core dump while attempting to delete an Layer-3 flow entry; it may be unable to
find the entry, or it may find a faulting address.
F0443
If a link is disconnected and then reconnected while the X-Pedition is passing traffic, Layer-3 entries
may not be deleted correctly. If routing is configured, the X-Pedition will fail to redirect traffic to a
new route.
F1358
Layer-4 Bridging I.D.
When operating in Layer-4 bridging mode via the vlan enable l4-bridging configuration command,
the user must only employ the default address-bridging mode for Layer-2 learning on ports in the
Layer-4 bridging VLAN. In addition, the user must not apply the port flow-bridging <port-list>
command to any ports in an Layer-4 VLAN.
NOTE: This restriction exists only for T-Series line cards. These cards are recognizable by the “T”
printed upon them.
F0760
Link-Aggregation Control Protocol (LACP) I.D.
LACP SmartTRUNK will not connect to a destination router when located on a line card in slots 9-16
of the X-Pedition ER16. Unlike Huntgroup protocol SmartTRUNKs, LACP SmartTRUNKs should
function in the upper slots.
