Enabling a Catena Instance
Before You Begin
Check that you have completed the following:
Purpose
• vlan-group vg-name—Specifies the VLAN group.
• ingress-port-group ipg-name—Specifies the ingress port group.
• egress-port-group epg-name—Specifies the egress port group.
• mode mode—Specifies the mode types-drop, bypass, or forward -
for the received packets.
• load-balance —Specifies the type of load balancing for catena traffic.
◦port-channel—Specifies hash based load balancing.
◦src-ip | dst-ip—Specifies TCAM based load-balancing.
The first example describes a transparent mode (Layer 2) service chain.
A Layer 2 chain requires that you create and define both a port and a
VLAN group.
The second example describes a routed mode (Layer 3) chain. A Layer 3
chain requires that you create and define both a port and an egress device
group.
Currently, you must configure separate instances for Layer 2 and Layer
3 modes.
A catena instance can comprise multiple chains that are independent of
each other. The traffic in each chain is forwarded as defined. However, if
there is an overlap between packets from different chains at the ingress
port, then all the chains configured on that ingress interface will be
evaluated. If a match is found on the ingress interface, then the matching
chain is accepted and forwarded.
Enables the catena instance.
(Optional)
Copies the running configuration to the startup configuration.
