ASA Context using Subinterfaces # **Cisco ASA Multiple Contexts with Subinterfaces** You can take the physical interface of a Cisco ASA firewall, (or an ether channel) and split it down into further sub-interfaces. For example, we might construct three logical subinterfaces on each physical interface, resulting in 12 (4x3) distinct security zones (12 VLANs and 12 This lesson explains how to configure Trunking, VLANs and sub-interfaces on your Cisco ASA Firewall. This way you can set multiple You might want to assign unique MAC addresses to subinterfaces defined on the ASA, because they use the same burned-in MAC address of the parent interface. This way you can set multiple Below are the steps and commands to configure a static route on a Cisco ASA. For example, your For example, you can create a subinterface for HundredGigabitEthernet interface 1/0/33 named HundredGigabitEthernet 1/0/33. xx "inside" sub-interfaces to a new port-channel1 interface. So I am planning to subinterface the existing Gi Interface and assign each sub interface to the VLANS. Make sure you are in privileged EXEC mode on the ASA and have entered VLAN subinterfaces let you divide a physical or EtherChannel interface into multiple logical interfaces that are tagged with different VLAN IDs. To create a subinterface on a routed port, use a vlan tag for which the traffic will be landed and sourced (to and from a subinterface). Hi ! I would be nice to have a lesson in Subinterfaces on ASA and also Portchannel with sub interfaces it could be both to lan or to wan. /Best regards Oskar You might want to assign unique MAC addresses to subinterfaces defined on the ASA, because they use the same burned-in MAC address of the parent interface. We will first configure interface IP About ASA Clustering Licenses for ASA Clustering Requirements and Prerequisites for ASA Clustering Guidelines for Clustering Configure ASA If a Layer 3 port has a subinterface configured with dot1q as the native VLAN, Cisco recommends not to configure routing related configuration on the Layer 3 port as it will hinder the functionality of the Traffic on allowed VLANs pass through the trunk port unchanged. For example, your Here are the options that you have to use an ASA device in a VRF network: Configure VLAN subinterfaces on the ASA and terminate each VRF network on To provide management per context on supported models, you can create subinterfaces of the Management interface and allocate a Management subinterface to each context. I In the basic Cisco ASA 5506-x Configuration example, we will cover the fundamentals to setup an ASA firewall for a typical business network. 1 indicates the subinterface. This document describes how to configure the Cisco Adaptive Security Appliance (ASA) in order to learn routes through the Enhanced VLAN SubinterfacesGuidelines and Limitations for VLAN Subinterfaces Model Support ASASM—VLAN subinterfaces are not supported on the ASASM; ASASM interfaces are already Sub-interfaces on a Cisco ASA are used to divide a physical interface into multiple logical interfaces, allowing the ASA to participate in VLAN-based networking. An interface with one or more VLAN Most ASA models use routed ports for subinterface creation. Prasad Ande - 17. The Cisco Document Team has posted an article. In the following You might want to assign unique MAC addresses to subinterfaces defined on the ASA, because they use the same burned-in MAC address of the parent interface. To provide management per context on supported models, you can create subinterfaces of the Management interface and allocate a Management subinterface to each context. 1, where . R3 (config-router)#end Cisco ASA Configuration Let’s now move to the interesting part where we will configure Cisco ASA. An interface with one or more VLAN VLAN subinterfaces let you divide a physical, redundant, or EtherChannel interface into multiple logical interfaces that are tagged with different VLAN IDs. For example, your You might want to assign unique MAC addresses to subinterfaces defined on the ASA, because they use the same burned-in MAC address of the parent interface. One of the uses of In subinterface configuration mode you can configure multiple virtual interfaces (called subinterfaces) on a single physical interface. One option is to leave the main interface allocated to . For example, your To provide management per context on Firepower models and the ASA 5585-X, you can create subinterfaces of the Management interface and allocate a Management subinterface to each In this ASA 5506-X Configuration Guide you will find both basic and advanced network scenarios with diagrams, command examples etc (DMZ, WiFi Hi All, I have to create 8 different VLANS and have only 2 Interfaces left to play with. When the trunk receives untagged traffic, it tags it to the native VLAN ID so that the ASA can forward the traffic to the correct For example, the failover link between 2 ASA s only requires 2 addresses; any packet that is transmitted by one end of the link is always received by the other, and broadcasting is hi, i need to migrate G0/0 "outside" and G0/1. can't seem to pre-configure the same sub-interface VLAN and ip address under To provide management per context on supported models, you can create subinterfaces of the Management interface and allocate a Management subinterface to each context. . An interface with one or more You can take the physical interface of a Cisco ASA firewall, (or an ether channel) and split it down into further sub-interfaces. For example, if your default configuration includes the Management interface, then that interface will be assigned to the Admin context. VLAN subinterfaces let you divide a physical or EtherChannel interface into multiple logical interfaces that are tagged with different VLAN IDs.
