Fig 1-6 application of VSF in the campus data center
Fig 1-6 is the application of VSF in the campus internet. After using the VSF, it groups several f
acilities together to become the single logic facility and connect to the virtual facility. After the predige
stion, the network do not need to use MSTP, VRRP protocol, it simplifies the network configuration. A
t the same time, it relies on the cross facilities to aggregate the link (The active mode must be used
for port group). When some of the members are out of order, it will not rely on MSTP, VRRP proto
col etc constringency, thus in increase the reliability.
74.1.5 LACP MAD
lacp mad is the dynamic aggregation method based on lacp. Each member device of vsf has on
e port connecting to the middle device at least.
Notice: The middle device must be the device which supports the extended function of lacp.
