Configuration restrictions and guidelines
When you configure VXLAN IP gateways, follow these restrictions and guidelines:
Device role | Configuration | Restrictions and guidelines |
---|---|---|
VXLAN IP gateway | Ethernet service instance and access mode |
|
Priority trust mode | A VXLAN IP gateway processes the DSCP precedence in frames received from an AC as follows:
| |
PBR | A PBR policy cannot match VXLAN packets by the source and destination IP addresses in the outer IP header on a Layer 3 interface (VSI interfaces not included). To match VXLAN packets by the source and destination IP addresses in the outer IP header, apply a PBR policy to a VSI interface. | |
VTEP | PBR | On a Layer 3 interface, a PBR policy cannot match VXLAN packets by the source and destination IP addresses in the outer IP header. |
Border gateway | ACL | An ACL applied to a Layer 3 Ethernet interface or Layer 3 aggregate interface matches packets on both the interface and its subinterfaces. For more information about ACLs, see ACL and QoS Configuration Guide. |
QoS |
| |
PBR | A PBR policy applied to a Layer 3 Ethernet interface or Layer 3 aggregate interface takes effect on both the interface and its subinterfaces. For more information about PBR, see Layer 3—IP Routing Configuration Guide. | |
Storm suppression | Broadcast, multicast, or unknown unicast storm suppression configured on a Layer 3 Ethernet interface takes effect on both the interface and its subinterfaces. For more information about storm suppression, see Layer 2—LAN Switching Configuration Guide. | |
MAC address assignment | Do not use the mac-address command to assign MAC addresses to the following interfaces:
| |
ARP | You cannot execute the arp mode uni command on interfaces of a Layer 3 border gateway. For more information about this command, see ARP commands in Layer 3—IP Services Command Reference. |
