Figure 7.3: Layer 3 Switch
The S50layer3 script executes the following commands:
• Runs zconfig command to create 24 untagged VLANs (one for each switch port).
/usr/sbin/zconfig zhp0..23: vlan1..24=zre0+
/usr/sbin/zconfig zre0..23=untag1+
NOTE: Double periods (..) after vlan1 and untag1 are used to indicate a range of values.
The plus (+) sign after zre1 is a wildcard character that means auto-incremented and
causes each zhp interface to hold only one zre (that is, zhp0 has zre1 on vlan1,
zhp1 has zre1 on vlan2).
• Runs the Linux ifconfig(1M) command for each interface to assign default IP
addresses (10.0.0.42-10.0.23.42), sets the netmask and brings up the interfaces.
ifconfig zhp0 10.0.00.42 netmask 255.255.255.0 up
ifconfig zhp1 10.0.01.42 netmask 255.255.255.0 up
ifconfig zhp2 10.0.02.42 netmask 255.255.255.0 up
