Removing Units from an Existing Stack If the running stack uses a daisy chain topology, make the stack cable connections from the bottom of the stack to the new unit (that is, STACK DOWN port from the bottom unit of the running stack to the STACK UP port on the new unit). IP packets are not encapsulated in any further protocol headers as they transit the Autonomous System (AS). Configuring IRDP 21-8 IPv4 Basic Routing Protocols. Because port admin keys for all LAGs and the physical ports 4 - 6 are the same, physical ports 4 - 6 satisfy rule 2. Link Aggregation Overview Single Port Attached State Rules By default, a LAG must contain two or more actor and partner port pairs for the LAG to be initiated by this device. User Authentication Overview Figure 10-1 Applying Policy to Multiple Users on a Single Port Authentication Request User 1 Switch Authentication Response Radius Server SMAC 00-00-00-11-11-11 Authentication Credentials User 1 Authentication Credentials User 2 Authentication Request Authentication Credentials User 3 Authentication Response User 2 SMAC 00-00-00-22-22-22 Port ge.1.5 Authentication Request User 3 Dynamic Admin Rule for Policy 1 SMAC = 00-00-00-11-11-11 ge.1. You can configure ports to only use MDI or MDIX connections with the set port mdix command. This procedure would typically be used when the system is NOT configured for routing. Enterasys S8-Chassis Manuals & User Guides User Manuals, Guides and Specifications for your Enterasys S8-Chassis Chassis. This setting is useful for configuring more complex VLAN traffic patterns, without forcing the switch to flood the unicast traffic in each direction. Interpreting Messages Every system message generated by the Enterasys switch platforms follows the same basic format: time stamp address application [unit] message text Example This example shows Syslog informational messages, displayed with the show logging buffer command. Table 8-3 Link Flap Detection Show Commands Task Command Display whether the port is enabled for generating an SNMP trap message if its link state changes. [egress-vlans egressvlans] forbidden-vlans (Optional) Specifies the port to which this policy profile is applied should be added as forbidden to the egress list of the VLANs defined with this parameter.

Refer to the CLI Reference for your platform for more information about these commands. Configuration Digest 16-octet HMAC-MD5 signature created from the configured VLAN Identification (VID)/Filtering Identification (FID) to Multiple Spanning Tree Instances (MSTI) mappings. When bridges are added to or removed from the network, root election takes place and port roles are recalculated. Using the output of the show switch switchtype command, determine the switch index (SID) of the model of switch being configured. Configuring PIM-SM PIM-SM is an advanced routing feature that must be enabled with a license key. 9 Configuring VLANs This chapter describes how to configure VLANs on Enterasys fixed stackable and standalone switches. Quality of Service Overview queue 2 has access to its percentage of time slices, and so on round robin. Highly accomplished Network engineering professional with 10+ years of experience in designing, deploying, migrating and supporting critical systems. The router with the highest priority is elected the DR, and the router with the next highest priority is elected the BDR. , ./ `. The hello interval is the period between transmissions of hello packet advertisements. Transferring switch configurations Using the CLI commands described in the section beginning with TFTP: Copying a configuration file to a remote host (CLI), you can copy switch configurations to and from a switch, or copy a software image to configure or replace an ACL in the switch configuration. SNTP Configuration Use the set sntp authentication key command to configure an authentication key instance. set arpinspection vlan vlan-range [logging] 3. 4. UsethiscommandtodisplaySNMPtrafficcountervalues. Diffserv Disabled. Basic Network Monitoring Features Network Diagnostics Fixed Switch network diagnostics provide for: Pinging another node on the network to determine its availability Performing a traceroute through the IP network to display a hop-by-hop path from the device to a specific destination host Use the ping command, in switch mode or in router privileged exec mode, to determine whether the specified node is available.

For an IPv6 ACLs, the following protocols can be specified in a rule: Any IPv6 protocol Transmission Control Protocol (TCP) User Datagram Protocol (UDP) IPv6 Internet Control Message Protocol (ICMPv6) TCP and UDP rules can match specific source and destination ports. Connecting to the Switch If the adapter cable requires a driver, install the driver on your computer. Do you want to continue (y/n) [n]? Port Configuration Overview By default, Enterasys switch devices are configured to automatically detect the cable type connection, straight through (MDI) or cross-over (MDIX), required by the cable connected to the port. Understanding How VLANs Operate Forwarding Decisions VLAN forwarding decisions for transmitting frames is determined by whether or not the traffic being classified is or is not in the VLANs forwarding database as follows: Unlearned traffic: When a frames destination MAC address is not in the VLANs forwarding database (FDB), it will be forwarded out of every port on the VLANs egress list with the frame format that is specified. Port Traffic Rate Limiting You can mix WRR and SP by assigning SP to the higher numbered queues and assigning WRR to the lower numbered queues, making sure that the values assigned to the WRR queues totals 100 percent. 10 Configuring User Authentication This chapter describes the user authentication methods supported by Enterasys fixed switch platforms. Table 25-3 lists the tasks and commands. Neighbor Discovery Overview There are two primary LLDP-MED device types (as shown in Figure 13-2 on page 13-5): 13-4 Network connectivity devices, which are LAN access devices such as LAN switch/routers, bridges, repeaters, wireless access points, or any device that supports the IEEE 802.1AB and MED extensions defined by the standard and can relay IEEE 802 frames via any method. Some of the most useful ones include: True zero-touch configuration; Integrated troubleshooting tools, logging, and alerting ; Energy-efficient design The key is an alphanumeric string of up to 8 characters. 18 Configuring Network Monitoring This chapter describes network monitoring features on the Fixed Switches and their configuration. i . The trap indicates port, SID and loop protection status. DHCP Configuration 192.168.10.10 1 1 Active DHCP Configuration Dynamic Host Configuration Protocol (DHCP) for IPv4 is a network layer protocol that implements automatic or manual assignment of IP addresses and other configuration information to client devices by servers. The VLAN authorization table will always list any tunnel attributes VIDs that have been received for authenticated end systems, but a VID will not actually be assigned unless VLAN authorization is enabled both globally and on the authenticating port. Connect the adapter cables USB connector to a USB port on your PC or laptop and determine which COM port has been assigned to that USB port. Table 15-5 on page 15-19 defines the characteristics of each MSTI. Considerations About Using clear config in a Stack To create a virtual switch configuration in a stack environment: 1. Refer to page Security Mode Configuration FIPS mode is disabled by default. Valid sid values are 04094. This enables you to set the IP address and system password using a single console port.
