Mtu - H3C MSR 810 Command Reference Manual

Usage guidelines
A remote MAC address is the MAC address of a VM in a remote site. Remote MAC entries include
manually added MAC entries, dynamically learned MAC entries, and MAC entries advertised
through a protocol, for example, BGP EVPN.
When you add a remote MAC address entry, make sure the specified VSI's VXLAN has been
assigned the specified VXLAN tunnel.
The
undo mac-address static vsi vsi-name
entries for a VSI.
Do not configure static remote-MAC entries for tunnels that are automatically established by using
EVPN.
•
EVPN re-establishes tunnels if the transport-facing interface goes down and then comes up. If
you have configured static remote-MAC entries, the entries are deleted when the tunnels are
re-established.
•
EVPN re-establishes tunnels if you perform configuration rollback. If the tunnel IDs change
during tunnel re-establishment, configuration rollback fails, and static remote-MAC entries on
the tunnels cannot be restored.
Examples
# Add MAC address 000f-e201-0101 to VSI vsi1. Specify Tunnel-interface 1 as the outgoing
interface.
<Sysname> system-view
[Sysname] mac-address static 000f-e201-0101 interface tunnel 1 vsi vsi1

size
Usage guidelines
The MTU set by using this command limits the maximum length of the packets that a VSI receives
from ACs and forwards through VXLAN tunnels. The MTU does not limit the maximum length of
other packets in the VXLAN VSI.
