Troubleshooting the SWAN Concentrator and WAN Subsystem

Starting the WAN Subsystem Processes and Objects
This procedure describes how to start the required WAN subsystem processes and objects. It also
describes how to start the processes and objects that support a ServerNet wide area network (SWAN)
concentrator (for example, Ethernet 4 ServerNet adapters (E4SAs), Fast Ethernet ServerNet adapters
(FESAs), TCP/IP processes, and so forth).
Note: Angle brackets (for example, <line-name>) are used in command syntax to indicate values that
you must provide.
1 To start the WAN manager process, use the SCF START PROCESS command:
START PROCESS $ZZKRN.#ZZWAN
2 To start the LAN manager process, use the SCF START PROCESS command:
START PROCESS $ZZKRN.#ZZLAN
3 To start the E4SAs or FESAs to which the SWAN concentrator is connected:
Use the SCF START ADAPTER command with the SUB ALL option:●
START ADAPTER $ZZLAN.<adapter-name1>, SUB ALL
START ADAPTER.$ZZLAN.<adapter-name2>, SUB ALL
Use the SCF START LIF command to start the logical interfaces (LIFs) used by the
SWAN concentrator on each E4SA or FESA:
●
START LIF $ZZLAN.<lif-name1>
START LIF $ZZLAN.<lif-name2>
4 To start the TCP/IP stacks associated with each LIF:
If a preferred and/or alternate TCP/IP process no longer exists, you must recreate it
using the following TACL commmand:
●
TCPIP / NAME $<tcpip-process>, NOWAIT,
CPU <primary-cpu-num>, PRI <priority-num>,
TERM $ZHOME / <backup-cpu-num>
Note: Always run TCP/IP as a process pair. Otherwise, the TCP/IP process
loses all LAN access if the data path to the LIF changes.
If the subnets associated with the LIFs are not started, use the SCF START SUBNET
command to start them:
●
START SUBNET $<pref-tcpip-process>.#<subnet-name>
START SUBNET $<alt-tcpip-process>.#<subnet-name>
If the routes on the preferred and alternate TCP/IP processes are not started, use the
SCF START ROUTE command to start that them:
●
START ROUTE $<pref-tcpip-process>.#<route-name>
START ROUTE $<alt-tcpip-process>.#<route-name>
5 To start that the SNMP agent processes that support the SNMP trap multiplexer processes,
use the SCF START PROCESS command:
START PROCESS $<snmp-agent-process>
