3.1.10 mac-table limit

Syntax
mac-table limit mac-limit-num
View
VSI-LDP view
Parameter
mac-limit-num: Maximum number of the MAC addresses of a specific VSI.
Description
Use the mac-table limit command to configure the maximum number of the MAC
addresses in the VPN. This number ranges from 0 to 65,535 and defaults to 128. When
the total number of the MAC addresses of the VSI exceeds this number, the system no
longer learns any new source MAC address; instead, it directly broadcasts the packet
in the VSI.
Example
# Set the maximum number of the MAC addresses of the VPLS instance Huawei to
1,024.
[Quidway-vsi-Huawei-ldp] mac-table limit 1024

3.1.11 mtu

Syntax
mtu mtu
View
VSI-LDP view
Parameter
mtu: Value of the access maximum transmission unit (MTU) of a VPLS instance, in the
range of 128 bytes to 8192 bytes. By defaults, MTU is 1,500 bytes.
Description
Use the mtu command to specify the MTU value for user access packets of this VPLS
instance. This mtu value is also the mtu value for PW.
MTU value is a global characteristic of a VPLS instance, and all the MTU values of the
peer PEs of the instance must be consistent.
