Restrictions In Card Intermixing - H3C S9500 Series Operation Manual

Operation Manual – MPLS
H3C S9500 Series Routing Switches
only VLANs with two ports: one is the source port (port of the non-MPLS card) and
the other is the destination port (port of the MPLS card);
When the source port (Trunk port) in intermixing networking belongs to multiple
VLANs, VPN binding must be implemented on the VLAN interfaces after the
redirection configuration;
If VRRP is configured on the VLAN interface to which the redirected source port of
the MPLS VPN belongs, the plugging/unplugging of the MPLS card will cause
VRRP group state switching on the VLAN interface.

5.2.2 Restrictions in Card Intermixing

Source port aggregation and destination port aggregation are not supported;
Nested VPN is not supported;
Super VLAN is not supported;
It is not allowed to change the attributes of the redirected source port;
It is not allowed to make the redirected source port or destination port to leave
redirected VLAN in the normal way;
It is not allowed to configure protocol VLANs on the redirected source port or
destination port;
It is not allowed to delete the redirected VLAN or VLAN interface;
It is not allowed to configure/add Loopback ports in the redirected VLAN;
It is not allowed to use STP edge port as the redirected destination port;
It is not allowed to change the VLANs and the default VLAN ID which the
redirected destination port is permitted to pass;
If normal ports are used, 4,094 VLL VPNs are supported; if the Trunk port of the
card of a fast Ethernet card is used, a maximum of 1024 VLL VPNs are supported;
Only cards with suffix CA can be used at the public network side for VLL
configuration;
Redirection configuration for MPLS VPN intermixing is not supported on the POS
and RPR ports, and the POS port cannot be used as the destination port for MPLS
VPN redirection;
A Trunk-type 100M Ethernet port can use only 1024 VLANs for VPN access or MPLS
forwarding, but you can specify the start VLAN ID of the 100M Ethernet Trunk port.
Assume the start VLAN ID is VLAN ID, the range of VLAN IDs of the VLANs that pass a
certain 100M Ethernet port is from VLAN ID to VLAN ID + 1023.
