vlan-mapping modulo
Use vlan-mapping modulo to map VLANs in the MST region to MSTIs according to the specified modulo
value, quickly creating a VLAN-to-instance mapping table.
Syntax
vlan-mapping modulo modulo
Default
All VLANs are mapped to the CIST (MSTI 0).
Views
MST region view
Default command level
2: System level
Parameters
modulo: Sets the modulo value.
The following matrix shows the value range for the modulo argument on different firewalls and firewall
modules:
Hardware Value ran
g
e
F1000-A-EI/F1000-S-EI 1 to 15
F1000-E 1 to 15
F5000 1 to 15
F5000-S/F5000-C 1 to 15
VPN firewall modules 1 to 15
20-Gbps VPN firewall modules 0 to 15
Usage guidelines
You cannot map a VLAN to different MSTIs. If you map a VLAN that has been mapped to an MSTI to a
new MSTI, the old mapping will be automatically removed.
This command maps each VLAN to the MSTI whose ID is (VLAN ID – 1) %modulo + 1, where (VLAN ID
– 1) %modulo is the modulo operation for (VLAN ID – 1). If the modulo value is 15, for example, then
VLAN 1 will be mapped to MSTI 1, VLAN 2 to MSTI 2, VLAN 15 to MSTI 15, VLAN 16 to MSTI 1, and
so on.
