79.4 VSF Troubleshooting
For VSF, under the configuration and usage, the command may not be workable, please pay attention
to the following items:
 Whether it is at the operation mode, because some of the commands can only be configured at
VSF operation mode, but some of them can operation at both VSF and independent operation
mode.
Under the failure of VSF during the VSF processes, or appear any abnormity, please pay attention to the
following thing:
 First, need to check whether physical connection is correct. Right now, the group VSF machine can
only support million-mega port or logic port colligate. Please check whether the 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 things:
 During the VSF operation mode, VSF related configuration can be done on the each member
separately. However, the configuration done on the members cannot be saved independently. It
cans still excute the write function on the vsf master. All the membes’ personal 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, priority of
member, member id etc can still be configured or amended. After the configuration, the show run
displays as the latest value, it can only be effective as you restart the computer after saving.
For LACP MAD, under the configuration and usage, if there are problems, please pay attention to the
following items:
 When creating the aggregation group, the aggregation of the device which is detected and the
middle device must be identical.
 The ports of the device which is detected and the middle device cannot be added into the
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 (vsf domain
number) of the two vsf cannot be the same.
For BFD MAD, under the configuration and usage, if there are problems, please pay attention 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, etc). if this vsf
is configured anti-ring function, the ports used for bfd mad detection should be disabled the
anti-ring function, otherwise, the detection may fail.
 If there is port configured as truck port on this vsf (include port-channel port), please ensure
