Single Arm Installation of LTM

Hi Everyone,   I want to install the LTM in a single arm mode do I still need to create both "internal-vlan" and "external-vlan"??? or I can create only one vlan that is "internal"     I have...

in one arm installation there is no need for multiple VLAN's to keep as internal and external ????right??? yes

 

 

In case if I have a LTM fail-over unit, do i have to do these trunk configuration on the fail-over unit as well or it can get these configuration on synchronizing the two units. network configuration (e.g. vlan, non-floating selfip, trunk, etc) is not included in synchronization. you have to configure them maually.

 

 

Also in case of Active/Standby configuration can I keep the LACP mode as active on both of the units? or it should be Active on active unit and Passive on Standby unit????? LACP active mode on both sides is fine.

 

 

Now the problem is If i take out one port from each LTM unit and keep it for network fail-over as separate it will disturb my design as described above.can you use serial failover instead of network failover? if i were you and serial failover was not possible, i would use 2 ports for each cisco (4 ports totally), 2 ports for network failover and 2 ports for future use.
