On I-Series only, display contents of memory card. Quality of Service Overview Preferential Queue Treatment for Packet Forwarding There are three types of preferential queue treatments for packet forwarding: strict priority, weighted fair, and hybrid. If a RADIUS Filter-ID exists for the user account, the RADIUS protocol returns it in the RADIUS Accept message and the firmware applies the policy to the user. priority Sets which ports continue to receive power in a low power situation. Optionally, choose to discard tagged or untagged, (or both) frames on selected ports. Graft messages are sent upstream hop-by-hop until the multicast tree is reached. The two switches are connected to one another with a high speed link. MAC lock traps Specifies whether SNMP traps associated with MAC locking will be sent. A value of 0 means that two consecutive SPF calculations are performed one immediately after the other. Skilled in network testing and troubleshooting. Three ICMP probes will be transmitted for each hop between the source and the traceroute destination. set txqmonitor downtime seconds The default value is 0, meaning that disabled ports will remain disabled until cleared manually or until their next link state transition. When send-on-violation is enabled, this feature authorizes the switch to send an SNMP trap message if an end station is connected that exceeds the maximum values configured using the set maclock firstarrival and set maclock static commands. Use the set system lockout command to: Set the number of failed login attempts allowed before disabling a read-write or read-only user account or locking out a super-user account. Since there is no way to tell whether a graft message was lost or the source has stopped sending, each graft message is acknowledged hop-by-hop. The days of the week for which access will be allowed for this user. All routers with the same VRID should be configured with the same advertisement interval. Configuring IPv4 ACLs Procedure 24-1 describes how to configure IPv4 standard and extended ACLs. Configuration To configure this switch, use a serial terminal connection to its console port. Configuring IRDP Configuring IRDP Using IRDP in Your Network The ICMP Router Discovery Protocol (IRDP), described in RFC 1256, enables a host on multicast or broadcast networks to determine the address of a router it can use as a default gateway. Cisco Switch implementation and configuration (4000 series, 2950 . show ip dvmrp [route | neighbor | status] Display the IP multicast routing table. Assign to queue assign the packet to a queue Note: Unlike other Fixed Switch platforms, A4 ACLs are not terminated with an implicit deny all rule. This procedure would typically be used when the system is NOT configured for routing. Both: management-access and network-access. lacptimeout - Transmitting LACP PDUs every 30 seconds. The set inlinepower mode command is set to auto, which means that the power available for PoE (150W) is distributed evenly75W to each PoE module. By default, MAC authentication is globally disabled on the device. Port auto-negotiation Enabled on all ports. By enabling the link flap detection feature on your Enterasys switch, you can monitor and act upon link flapping to avoid these recalculations. This requires a minimum of two twisted pairs for a single physical link. .

This sets the port VLAN ID (PVID). If the authentication succeeds, the policy returned by authentication overrides the default port policy setting. After you have properly configured the switch, and started Enterasys WebView, you can perform any of the tasks described in the following sections. To perform a TFTP or SFTP download: 1. A graft retransmission timer expires before a graft ACK is received. When a root or alternate port loses its path to the root bridge, due to message age expiration, it takes on the role of designated port and will not forward traffic until a BPDU is received. (Optional) Specify the method the Enterasys device uses to detect connected PDs. Terms and Definitions 20-12 IP Configuration. Set to 30 seconds for non-broadcast networks. Periodically, say every second, the sFlow Agent examines the list of counter sources and sends any counters that need to be sent to meet the sampling interval requirement. Chapter Title. 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). Example CLI Properties Configuration In this example, the prompt is changed and a login banner is added. (Optional) Configure the allocation mode for system power available for PoE. Before attempting to configure a single device for VLAN operation, consider the following: What is the purpose of my VLAN design? UsethiscommandtodisplaytheswitchsARPtable.

Spanning Tree Basics RSTP Operation RSTP optimizes convergence by significantly reducing the time to reconfigure the networks active topology when physical topology or configuration parameter changes occur. You can enable link flap detection globally on your Enterasys switch or on specific ports, such as uplink ports. To determine if all these elements are in place, the SNMP agent processes a device configuration as follows: 1. Using Multicast in Your Network 19-1 Configuring IGMP 19-15 Configuring DVMRP 19-18 Configuring PIM-SM 19-21 Using Multicast in Your Network Multicast is a one source to many destinations method of simultaneously sending information over a network using the most efficient delivery strategy over each link. UsethiscommandtodisplaythesystemIPaddressandsubnetmask. Guest networking allows an administrator to specify a set of credentials that will, by default, appear on the PWA login page of an end station when a user attempts to access the network. SNTP Configuration Use the set sntp authentication key command to configure an authentication key instance.
