Most switches have multiple TCAMs so that both inbound and outbound security, as well as QoS ACLs, can be evaluated simultaneously, or entirely in parallel with a Layer 2 or Layer 3 forwarding decision. TCAM allows a packet to be evaluated against an entire access list in a single table lookup. Ternary Content Addressable Memory (TCAM)-In multilayer switches, all the processes that access control lists (ACLs) provide in traditional routing, such as matching, filtering, or control specific traffic, are implemented in hardware.

If a MAC address is found already present in the table for the correct arrival port, only its timestamp is updated. If a MAC address learned on one switch port has moved to a different port, the MAC address and timestamp are recorded for the most recent arrival port. The port of arrival and the VLAN are both recorded in the table, along with a timestamp. As frames arrive on switch ports, the source MAC addresses are learned and recorded in the CAM table. All hosts within the broadcast domain receive the ARP request, and only Host A responds with its MAC address.Д¬AM-All Catalyst switch models use a CAM table for Layer 2 switching. Host B generates a broadcast message for all hosts within the broadcast domain to obtain the MAC address associated with the IP address of Host A. For example, Host B wants to send information to Host A but does not have the MAC address of Host A in its ARP cache. Background InformationД¬atalyst switches maintain several types of tables that are tailored for Layer 2 switching or multilayer switching (MLS), and are kept in very fast memory so that many fields within a frame or packet can be compared in parallel.ДЄRP-Maps an IP address to a MAC address in order to provide IP communication within a Layer 2 broadcast domain.

Select the vLAN item and configure Promiscuous Mode, MAC Address Changes and Forged Transmits as specified.This document provides information on how to troubleshoot Address Resolution Protocol (ARP) or Content Addressable Memory (CAM) table-related issues on Catalyst 6500/6000 Switches.

For Promiscuous Mode, MAC Address Changes and Forged Transmits, configure them as shown in the tables above.

Select the vSwitch item in the Configuration list, and click Edit.

On the right side of the page, click Properties for the vSwitch to edit.

Click the Configuration tab and click Networking.

Just keep in mind that it may compromise the security of the network. However, it's allowed to change the settings from Reject to Accept because the traffic will not be affected in this way. It's suggested to exactly follow the configurations listed in the tables above, especially for the Accept settings, because changing the settings from Accept to Reject will lead to traffic disruption. Table 2: vSwitch and vLAN security policies when FortiWeb is deployed in True Transparent Proxy operation mode Table 1: vSwitch and vLAN security policies when FortiWeb is deployed in Reverse Proxy operation modeДЄctive-passive HA / active-active standard HA The following configurations apply to all ports except the ones for HA heartbeat and reserved management, because they use the MAC addresses and don't need to follow the Accept and Reject rules listed below. The configurations allow the VM to become part of a group and process traffic correctly if there is a failover. To include FortiWeb-VM deployed on an ESXi hypervisor in a high availability (HA) group, ensure that the vSwitch and vLAN Promiscuous Mode, MAC Address Changes and Forged Transmits security policies are configured as shown in the following tables.
