CirrusWhat's the difference "Virtual Wire" and "VLAN group(Transparent) "
What's the difference "Virtual Wire" and "VLAN group(Transparent) "?
Please tell me easily!
I just know difference simply.
vlan-group can create self-ip.
and virtual-wire can`t create self-ip.
that difference cause difference result.
1) virtual-wire can`t health check.
-> to do HC, you have to using other interface and considering lots of things.
2) vlan-group function is basically arp-proxy architecture. transparent was little different.
-> If your L2 layer knowledge was poor, very hard to trouble shooting.
3) virtual-wire feature support over i5600.(not correct bigip 5000 series support too.)
If you have other question, let`s discuss!

Hello,
Do you know whether or not the virtual wire also disable the PVA acceleration automatically(like vlan-group does), if we have confgigured FatL4 virtuals?
I'm wondering which one has better performance.
rob_carrA VLAN group is used to forward traffic between two disparate VLANs, and can have self IP addresses associated with it.
A virtual-wire can be used to forward traffic between two interfaces, typically both with the same 802.1q tag. According to documentation, not all iSeries platforms support the virtual-wire option.
dum0785Thanks, answering.
Is the meaning the same otherwise?

Oh, it's OK. I use i2600 this time.

i2600 didn`t support virtual-wire.
virtual-wire feature support hardware platform over i5000

vlan group and virtual wire are used for transparent topology.
to use vlan group, have to create 2 vlans. ex) ext int
-> both ext int vlan is same broadcast-domain.
-> In normal case, each vlan have different broadcast-domain.
and create vlan-group with member ext int name VG
and you can create self-ip with vlan->VG.
If you consider HA pair, have to consider loop topology.
And you have to configure exclusive IP address each bigip`s self-ip.
