Managing Mac Address Entries; Enabling Local-Mac Change Logging - H3C S7500E-XS Series Configuration Manual

Step
6. Configure a frame match
criterion.
7. Map the Ethernet service
instance to a VSI.

Managing MAC address entries

With VXLAN, local MAC addresses are learned dynamically. You can log MAC changes, but you
cannot manually add local MAC addresses.
Remote-MAC address entries include the following types:
•
Manually created static entries.
•
Dynamic entries learned in the data plane.
•
MAC entries issued by a remote controller through OpenFlow.

Enabling local-MAC change logging

Local-MAC change logging enables the VXLAN module to send a log message to the information
center when a local MAC address is added or removed.
With the information center, you can set log message filtering and output rules, including output
destinations. For more information about configuring the information center, see Network
Management and Monitoring Configuration Guide.
To enable local-MAC change logging:
Step
1. Enter system view.
2. Enable local-MAC
change logging.
Command
•
Match frames that do not match
any other service instance on the
interface:
encapsulation default
•
Match any 802.1Q tagged or
untagged frames:
encapsulation { tagged |
untagged }
•
Match frames tagged with the
specified outer 802.1Q VLAN ID:
encapsulation s-vid vlan-id
[ only-tagged ]
•
Match frames tagged with the
specified outer and inner 802.1Q
VLAN IDs:
encapsulation s-vid vlan-id
c-vid vlan-id
xconnect vsi vsi-name
[ access-mode { ethernet | vlan } ]
Command
system-view
vxlan local-mac report

Remarks
By default, an Ethernet service
instance does not contain a
frame match criterion.
To match frames from a VLAN
correctly, make sure you have
created the VLAN and assigned
the interface to the VLAN.
To match untagged frames
when the VLAN access mode is
used, you must use the
encapsulation untagged
command.
By default, an Ethernet service
instance is not mapped to any
VSI.
If you set the match criterion to
default or tagged, you must
specify the Ethernet access
mode.
If you do not specify an access
mode, the default VLAN access
mode is used.
Remarks
N/A
By default, local-MAC change
logging is disabled.
