Every subinterface may have an own security level; sure you may have different security level for every interface.

I hope this helps.

Best regards.


No, it does not, when you set the security levels for sub interfaces, it does not have any interaction with the security level set on the physical interfaces. Routing is not possible between these interfaces unless you want this to happen then you use a certain command in the ios, if you need this command let me know and i will point you in right direction.

No,the security level of physical interface shouldn't affect the security level of sub-interfaces.

interface Ethernet0

nameif outside

security-level 0

no ip address

pixfirewall(config-if)# show run int e0.1


interface Ethernet0.1

vlan 2

nameif vlan2

security-level 25

no ip address

pixfirewall(config-if)# show nameif

Interface Name Security

Ethernet0 outside 0

Ethernet0.1 vlan2 25
