3.3.22. route
The “route” command is similar to analogous Linux command. It
is used to configure the IP routing,. The “route” alone shows the current
routing table. It may be modified using following commands:
¡
route add <address> <interface> - adds the route to a
specific host directly through the interface (the station with this
address has to be in the network directly connected to that
interface)
¡
route add <address> gw <gateway> - adds the route to a
specific host through a gateway
¡
route add -net <address> netmask <network mask>
<interface>
- adds the route to a subnet with given address and
network mask directly through a specified interface
¡
route add -net <address> netmask <network mask> gw
<gateway>
- adds the route to a subnet with given address and
network mask through a specified gateway
¡
route add default gw <address> - adds the default route
through a given gateway
¡
route del <address> - removes route to an IP address given
¡
route del -net <address> netmask <network mask> -
removes route to a subnet specified
¡
route del default - removes default route
3.3.23. serial
The command is used to select the V.35 port protocol:
¡
serial fr - Frame Relay
¡
serial ppp - synchronous PPP
®
¡
serial hdlc - Cisco HDLC
¡
serial raw - raw HDLC, without any headers or keepalive packets
3.3.24. snmp
The “snmp” command is used to configure the SNMP (Simple
Network Management Protocol) support. It has following syntax:
¡
snmp - shows current settings:
Tahoe> snmp
SNMP on
Read community: public
Write community: private
19
SNMP host1: <any>
SNMP host2: <disabled>
SNMP host3: <disabled>
¡
snmp on - enables SNMP support
¡
snmp off - disables SNMP support
¡
snmp rdcomm <text > - sets the read community - the
password used to read the SNMP parameters
¡
snmp wrcomm <text> - sets the write community - the
password used to write the SNMP parameters
¡
snmp host1 <address>
¡
snmp host2 <address>
¡
snmp host3 <address> - allows setting of up to 3 addresses,
from which the SNMP access will be permited. Entering 0.0.0.0
allows access from any address, while 255.255.255.255 disables
an entry (entering 255.255.255.255 in all three positions is equal
to disabling the SNMP service)
3.3.25. strictarp
The “strictarp” command helps protecting the LAN against the
unauthorized access. After enabling the “strictarp” mode (by typing
”strictarp on” ) and entering the static IP-MAC assignments (using “arp
add”) the router would listen to incoming ARP requests asking for the
addresses it has in its static table. If the request comes from another
MAC address than in the router’s ARP table, it will send an answer with
the correct MAC address.
®
Such request is sent by the PCs working under the Microsoft
Windows™ operating system during the boot-up. If the ARP reply from
the router comes, the PC will show a message that this address is
occupied, which will make an illegal use of that IP address impossible.
The “strictarp” mode may be disabled using
“strictarp off”.
3.3.26. syslog
The router may send the messages about its status and important
events to a syslog server. To configure syslog logging following
commands may be used:
¡
syslog on - enables logging
¡
syslog off - disables logging
¡
syslog host <IP address> - sets the IP address to which the
messages will be sent
