Cisco asa 5510 setup guide10/31/2022 ![]() Do not enter the no form, because that command causes all commands that refer to that name to be deleted. You can change the name by reentering this command with a new value. The name is a text string up to 48 characters, and is not case-sensitive. Step 3 Assign the name to interface using nameif name command. You cannot assign the same interface to more than one bridge group. You can assign up to four interfaces to a bridge group. Step 2 Assign the interface to a bridge group, where number is an integer between 1 and 100. In multiple context mode, enter the mapped_name if one was assigned using the allocate-interface command.Ĭiscoasa(config)# interface gigabitEthernet 0 Append the subinterface ID to the physical or redundant interface ID separated by a period (.). Step 1 If you are not already in interface configuration mode, enter the interface configuration mode using interface command, where redundant number is the redundant interface ID, such as redundant 1 and the port-channel number argument is the EtherChannel interface ID, such as port-channel 1. #CISCO ASA 5510 SETUP GUIDE HOW TO#The following procedure describes how to set the name, security level, and bridge group for each transparent interface. Therefore, if you use a /30 subnet and assign a reserved address from that subnet to the upstream router, then the ASA drops the ARP request from the downstream router to the upstream router. The ASA drops all ARP packets to or from the first and last addresses in a subnet. Also, do not use other subnets that contain fewer than 3 host addresses (one each for the upstream router, downstream router, and transparent firewall) such as a /30 subnet (255.255.255.252). Step 1 Create a bridge group using interface bvi bridge_group_number, where bridge_group_number is an integer between 1 and 100. To configure Bridge Group, follow the steps shown below: #CISCO ASA 5510 SETUP GUIDE FULL#For IPv6 traffic, you must configure the link-local addresses to pass traffic at minimum, but a global management address is recommended for full functionality, including remote management and other management operations. For IPv4 traffic, the management IP address is required to pass any traffic. The management IP address must be on the same subnet as the connected network. The ASA uses this IP address as the source address for packets originating from the bridge group. For example, all bridge groups share a syslog server or AAA server configuration.Įach bridge group requires a management IP address. ![]() ![]() Although the bridging functions are separate for each bridge group, many other functions are shared between all bridge groups. Bridge group traffic is isolated from other bridge groups traffic is not routed to another bridge group within the ASA, and traffic must exit the ASA before it is routed by an external router back to another bridge group in the ASA. If you do not want the overhead of security contexts, or want to maximize your use of security contexts, you can group interfaces together in a bridge group, and then configure multiple bridge groups, one for each network. Enter the changeto context_name command to change to the context you want to configure. For multiple context mode, complete the tasks in this section in the context execution space. ![]()
