CPU Utilization with XNS When the PathBuilder S5xx switch is configured for 2048 tunnels and XNS Protocol protocol, very high CPU utilization will occur.
IPX to
IPX Routing, Route When you route IPX over a Frame Relay meshed topology and configure the SAP Receive and Route Route Receive and Route Advertisement policies on the Frame Relay port, these
Advertisement Policies policies do not take effect until the SAP table is flushed.
Managing IP Address When assigning IP address to virtual ports of directly connected networks, it is Assignment important to ensure that the assigned address is valid. As LCP supports multiple
Network Control Protocols (NCPs), IP does not verify that the address is valid before bringing the port state up or down, as there may be other protocols which are utilizing that port. It is possible to have an UP port state, yet have a lack of IP connectivity.
NAT Service - Many to NAT Many to One Outbound does not translate properly when multiple addresses, One Outbound on LHS, are specified using comma (,) notation. But NAT Many to One Outbound Translation translates properly when multiple addresses, on LHS, are specified in 10.3.1.0/24
notation.
NAT Service - TCP/UDP When the NETBuilder bridge/router is configured to use TCP/UDP Port Mapping Port Mappings from port 23 (Telnet) to any other port number, the first command executed over
the session will fail due to extra characters inserted into the command string. All subsequent commands issued for that session will succeed. If you encounter this problem, execute the command again.
OSPF Route If your network is expecting more than 4000 OSPF routes you need to set the Advertisement ospfholdtime variable to 30.
This has the following implications.
