A router running DHCP client cannot obtain the default gateway address.
Auto configuring the Default gateway is not supported in this release. You
must manually configure this setting.
You cannot access certain web sites from DSL routers. To resolve this, set the
tcp maximum segment size to 1410 on the DSL router's outgoing (WAN)
physical or virtual interface.
IPX is not supported on Frame Relay, HDLC, and X25. IPX is only supported on
Ethernet and PPP.
The DHCP Server fails to remember the DHCP clients after a reboot.
OSPF interface costs are not the same on peer DCE/ DTE Frame Relay Serial
interfaces. If a Frame Relay DTE Serial interface is configured for OSPF, and the
DCE has a different baud rate, the interface must be configured with the
virtualbaudrate
rate as the DCE. After configuration, shut down and restart the interface.
BGP Auto-summary does not work for networks originated using the Network
command. Only imported routes will be auto-summarized.
An undo RIP from interface view removes RIP globally. To remove RIP from
interface view use the
BGP route dampening does not work for IBGP routes. BGP dampening works
for EBGP routes only.
The default value for the IGMP query interval does not match the
recommended value in RFC 2236. Set the query interval to match the query
interval of other routers in your network.
PIM is not supported with IP unnumbered FR interfaces. An IP address must be
assigned to the FR interface.
NAT traversal does not work in IKE Main Mode. IKE Aggressive Mode is
required for NAT traversal to function properly
IPsec tunnel will not get established with Cisco routers when a NAT device is in
the communications path. NAT traversal is not compatible with Cisco routers
Only one security association is used for all traffic flows. IPsec SAs originated
from 3Com routers will be ACL based. To obtain flow-based functionality,
create multiple ACLs with one rule each.
The firewall drops FTP connections when ASPF is configured to filter TCP.
Configure ASPF with TCP and FTP together
IPsec renegotiates SAs too early with heavy traffic. This may lead to traffic
disruptions. Set ISAKMP traffic (destination UDP port 500) as high priority in
QoS to avoid any disruption in communications through the IPsec tunnel
Frame Relay Classes that contain Frame Relay QoS parameters can be applied
to PVC's even if Frame Relay Traffic Shaping is not enabled. Frame Relay Traffic
Shaping must be enabled for PVC queues.
