• Verify port group is configured in the partner end, and in the same configuration. If the local end is set in manual aggregation or LACP, the same should be done in the partner end; otherwise part aggregation will not work properly. Another thing to note is that if both ends are configured with LACP, then at least one of them should be in ACTIVE mode, 269 otherwise LACP packet wouldn’t be initialed. • LACP cannot be used on port enabled Security and 802.1x, therefore it cannot be enabled if those two protocols are present on the port. • Port Channel Configuration 10.5 Web Management Click Port Channel configuration. LACP port group configuration node and LACP port configuration node are shown. LACP port group page is used to configure and show goupe; LACP port page is used to configure and show group member ports. 10.5.1 LACP port group configuration Click LACP port group configuration. The configuration page is shown. See the equivalent CLI command at 10.2.2.1 The explanation of each field is as below: Group Num - group number Load balance mode - Load balance mode: src-mac, dst-mac, dst-src-mac, src-ip, dst-ip and dst-src-ip Operation type - Add port group or Remove port group For example: Set group Num to 1; set Load balance mode to src-mac; set Operation type to Add port group, and then click Apply. After LACP port group is configured, the configuration is shown below. The explanation of each field is as below: port group - Port group load balance - Load balance mode 270 10.5.2 10.5.2 Click LACP port configuration. The configuration page is shown. See the equivalent CLI command at 10.2.2.2 The explanation of each field is as below: group num - Group number Port - Specify the port Port mode - Configure port mode: active, passive or on Operation type - Add port to group or Remove port from group For example: Set group num to 1; set Port to Ethernet 1/1; set Port mode to active; set Operation type to Add port to group, and then click Apply. Show member port After LACP port is configured, the configuration is shown below. See the equivalent CLI command at 10.4.1.1 The explanation of each field is as below: Port - Member port name Port mode - active, passive or on 271 Chapter 11 DHCP Configuration Chapter 11 DHCP Configuration Introduction to DHCP DHCP [RFC2131] is the acronym for Dynamic Host Configuration Protocol. It is a protocol that assigns IP address dynamically from the address pool as well as other network configuration parameters such as default gateway, DNS server, default route and host image file position within the network. DHCP is the enhanced version of BootP. It is a mainstream technology that can not only provide boot information for diskless workstations, but can also release the administrators from manual recording of IP allocation and reduce user effort and cost on configuration. Anther benefit of DHCP is it can partially ease the pressure on IP demands, when the user of an IP leaves the network, that IP can be assigned to another user. DHCP is a client-server protocol, the DHCP client requests the network address and configuration parameters from the DHCP server; the server provides the network address and configuration parameters for the clients; if DHCP server and clients are located in different subnets, DHCP relay is required for DHCP packets to be transferred between the DHCP client and DHCP server. The implementation of DHCP is shown below: Fig 11-1 DHCP protocol interaction Explanation: 1. DHCP client broadcasts DHCPDISCOVER packets in the local subnet. 2. On receiving the DHCPDISCOVER packet, DHCP server sends a DHCPOFFER packet along with IP address and other network parameters to the DHCP client. 3. DHCP client broadcast DHCPREQUEST packet with the information for the DHCP server it selected after selecting from the DHCPOFFER packets. 4. The DHCP server selected by the client sends a DHCPACK packet and the client gets an IP address and other network configuration parameters. The above four steps finish a Dynamic host configuration assignment process. However, if the DHCP server and the DHCP client are not in the same network, the server will not receive the DHCP broadcast packets sent by the client, therefore no DHCP packets will be sent to the client by the server. In this case, a DHCP relay is required to forward such 272 DHCP packets so that the DHCP packets exchange can be completed between the DHCP client and server. ES4626/ES4650 can act as both a DHCP server and a DHCP relay. DHCP server supports not only dynamic IP address assignment, but also manual IP address binding DHCP packets so that the DHCP packets exchange can be completed between the DHCP client and server. ES4626/ES4650 can act as both a DHCP server and a DHCP relay. DHCP server supports not only dynamic IP address assignment, but also manual IP address binding specify a specific IP address to a specified MAC address or specified device ID over a long period. The differences and relations between dynamic IP...
