756 VLANs
Step 9 should be configured on all ports connected to IP phones if using strict
priority or perhaps on all host facing ports if IP phones are moved frequently.
Do not configure steps 3 or 9 on inter-switch connections as they will be used
to aggregate voice traffic.
When configuring an MLAG for transport of voice VLAN traffic, remember
to configure steps 6-8 on the corresponding MLAG/Voice VLAN and both
ends of the MLAG peer link (or configure them globally on both peers and
the partner switches).

Figure 21-26 describes the reference topology. It is presumed that a call
manager of some type is connected to the network in the voice VLAN.
