Sub-interfaces on PO

Hi, I have put 2 physicl interfaces (te0/8 & 9) on the ASA-5585 into a PO and am assigning ips/vlans to the sub-interfaces. I have 2 issues: - Why am I not able to ping the other sub-interface from the ASA itself? (I can ping the 1st one), Secondly, why the IPs are not visible in "sh int ip brief" ?Although I can see them in "sh ip" ..

/actNoFailover(config-if)# int po17.100

/actNoFailover(config-subif)# vlan 100

/actNoFailover(config-subif)# ip add

/actNoFailover(config-subif)# ip address 100.1.1.1 255.255.255.0

/actNoFailover(config-subif)# int po17.101

/actNoFailover(config-subif)# vlan 101

/actNoFailover(config-subif)# ip address 101.1.1.1 255.255.255.0

/actNoFailover(config-subif)# int po17.102

/actNoFailover(config-subif)# vlan 102

/actNoFailover(config-subif)# ip address 102.1.1.1 255.255.255.0

/actNoFailover(config-subif)# ping 100.1.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 100.1.1.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 30/32/40 ms

/actNoFailover(config-subif)# ping 101.1.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 101.1.1.1, timeout is 2 seconds:

/actNoFailover(config)# sh int ip brie

Sub-interfaces on PO

Ok, i found the answer: - You have to assign "nameif" to the subinterfaces, they are pinging now and also  the ips are visible in "sh int ip brief".
