74.4 VSF Troubleshooting
For VSF, under the configuration and usage, the command may not be workable, please pa
y attention to the following items:
 Whether it is at the operation mode, because some of the commands can only be config
ured at VSF operation mode, but some of them can operation at both VSF and indepen
dent operation mode.
 Under the failure of VSF during the VSF processes, or appear any abnormity, please pa
y attention to the following thing:
 First, need to check whether physical connection is correct. Right now, the group VSF m
achine can only support million-mega port or logic port colligate. Please check whether t
he colligate port is the million-mega port.
 Whether the Vsf member id is clash, if the member ids are clashing, the facilities cannot
form vsf.
 Whether the Vsf domain numbers are same. Only the vsf domain numbers are identical,
the facilities can form the vsf.
 To see whether the logical port has any physical connection, for example, double speed,
bandwidth restriction, safety authentication, ACL etc configuration.
Under the VSF operation mode to undergo configuration, please pay attention to the following thi
ngs:
 During the VSF operation mode, VSF related configuration can be done on the each me
mber separately. However, the configuration done on the members cannot be saved inde
pendently. It cans still excute the write function on the vsf master. All the membes’ perso
nal configuration that is related to vsf will be save in the main computer’s vsf.cfg.
 Under the VSF operation mode, some of the commands such as VSF domain number, p
riority of member, member id etc can still be configured or amended. After the configurati
on, the show run displays as the latest value, it can only be effective as you restart the
computer after saving.
 Under the VSF operation mode, the active mode must be used for port group for ensuri
ng the fault convergence time.

For LACP MAD, under the configuration and usage, if there are problems, please pay atten
tion to the following items:
 When creating the aggregation group, the aggregation of the device which is detected an
d the middle device must be identical.
 The ports of the device which is detected and the middle device cannot be added into t
he aggregation with on mode for LACP MAD, one should be active method at least.
 When the device which is detected and the middle device are both vsf, the domain id (v
sf domain number) of the two vsf cannot be the same.

For BFD MAD, under the configuration and usage, if there are problems, please pay attenti
on to the following items:
 bfd mad function cannot be enabled under interface vlan 1.
 bfd mad function and the anti-ring function are mutually exclusive (such as stp, mstp, et
c). if this vsf is configured anti-ring function, the ports used for bfd mad detection should
