8 / 12 page Silicom Ltd. Connectivity Solutions Page 8 If there is external port that is heavily loaded the traffic will go into the 4 internal interfaces with balanced load. An ISL tag is added to all incoming packets, it enables the host to know the source port, and the ISL tag is removed from packets that are sent back from the host. Director – Tagged In-Line rule aware mode (*Future Support) Silicom’s 100 Gigabit Ethernet content aware director Provides intelligent packet redirection capability where rules specify which packets are directed to the host system and which packets are directed to the other ports (Bypass) but at the same time it will get these bypassed traffic into the host with a ISL tag marking that these packets are bypassed, per the rules that the host will issue to the Silicom’s 100 Gigabit Ethernet content aware director. Figure 5: Tagged In-Line rule aware mode Block Diagram Figure 5 illustrates functional block diagram of Tagged In-Line rule aware mode: Port Group (A,C,D), (B,E,F) configured as VLAN groups. Packets received in the 2 x 100G external ports (A and B) and meet and are directed to the other ports of the Vlan group with ISL tag that notify that match found. The original packet is sent to the “Output Port of Switch” in the rule matched policy Packets received in the 2 x 100G external ports (A and B) and do not meet the rule are directed to the other ports of the Vlan group taged with ISL tag that notify that no-match found. Director Capabilities The Redirector supports the following capabilities: Maximum total number of rules is 16K. Each of the 16K rules can be defined to any port the on board multi-layer switch. Each rule refers to incoming packet Rules are executed per order. First rule that matches will be executed Rules can be added and removed on the fly. Each rule can include one or more classification fields. A rule match will be when all fields defined are match. Each field can have a bit masking to check part of the classification field. Per port statistics can be read, like packets count, errors, VLAN, and more. Rules and action are done in wire speed at any packet size. |
