VLANs spanning two switches. On Switch 1, ports 1-4 are part of VLAN Accounting; ports 5 - 8 are part of VLAN Engineering. On Switch 2, ports 1-4 are part of VLAN Accounting; ports 5 - 8 are part of VLAN Engineering. VLAN Accounting spans Switch 1 and Switch 2 by way of a connection between Switch 1 port 2 and Switch 2 port 4.
Page 92: Uses Of Tagged Vlans
802.1Q tag defined, you decide whether each port will use tagging for that VLAN. The default mode of the switch is to have all ports assigned to the VLAN named “default,” with an 802.1Q VLAN tag (VLANid) of 1 assigned.

These VLANs are not permanently stored in NVRAM, and you cannot add or remove ports from these VLANs.
Page 97: Protocol-Based Vlans
ROTOCOL ASED Protocol-based VLANs enable you to define a packet filter that the Summit uses as the matching criteria to determine if a particular packet belongs to a particular VLAN. Protocol-based VLANs are most often used in situations where network segments contain hosts running multiple protocols.

STP topology. • All VLANs in each switch are members of the same STPD. STP may block traffic between Switch 1 and Switch 3 by disabling the trunk ports for that connection on each switch. Switch 2 has no ports assigned to VLAN marketing. Therefore, if the trunk for VLAN marketing on Switches 1 and 3 is blocked, the traffic for VLAN marketing will not be able to traverse the switches.
Page 115 ONFIGURING STP configuration involves the following actions: • Create one or more STP domains using the following command: create stpd <stpd_name> STPD, VLAN, and QoS profile names must all be unique. For example, a name used to identify a VLAN cannot be used when you create an STPD or a QoS profile.

The main benefit of QoS is that it allows you to have control over the types of traffic that receive enhanced service from the switch. For example, if video traffic requires a higher priority than data traffic, using QoS you can assign a different QoS profile to those VLANs that are transmitting video traffic.

UALITY OF ERVICE RIORITIZATION Prioritization is used when there is bandwidth contention for transmission on a port. The four levels of priority are used as a mechanism for resolving the contention between traffic groups. If traffic groups have the same priority, a “round-robin” algorithm is applied.
Page 127: Port Queue Monitor
You can assign a QoS profile to an IP address by using the following command: config ipqos [add | delete] <ip_destination_address> qosprofile <qosname> UEUE There are four queues per physical port in the Summit. In ingress mode, the four QoS profiles align to the four queues (for example, qp1 to the first queue, qp2 to the second queue, and so on).

ARP has been expended since its introduction. Currently, proxy ARP can be used to achieve router redundancy and simplify IP client configuration. The Summit switch supports proxy ARP for this type of network configuration. Up to 64 proxy ARP entries can be configured.
Page 135: Proxy Arp Between Subnets
• The valid IP ARP Request is received on a Summit router interface. • The target IP address matches the IP address configured in the proxy ARP table. • The proxy ARP table entry indicates that the switch should always answer this ARP Request (the parameter must be applied).

Page 149: Routing Protocols
Published by Addison-Wesley Publishing Company VERVIEW The Summit switch supports the use of either the Routing Information Protocol (RIP) or the Open Shortest Path First (OSPF) protocol for IP unicast routing. RIP is a distance vector protocol, based on the Bellman-Ford (or distance vector) algorithm.
Page 150: Rip Versus Ospf
OUTING ROTOCOLS RIP V OSPF ERSUS The distinction between RIP and OSPF lies in the fundamental differences between distance vector protocols and link state protocols. Using a distance vector protocol, each router creates a unique routing table from summarized information obtained from neighboring routers.
Page 151: Overview Of Rip
VERVIEW OF VERVIEW OF RIP is an Interior Gateway Protocol (IGP) first used in computer routing in the ARPAnet as early as 1969. It is primarily intended for use in homogeneous networks of moderate size. To determine the best path to a distant network, a router using RIP always selects the path that has the least number of hops.
Page 152: Triggered Updates
OUTING ROTOCOLS RIGGERED PDATES Triggered updates occur whenever a router changes the metric for a route, and it is required to send an update message immediately, even if it is not yet time for a regular update message to be sent. This will generally result in faster convergence, but may also result in more RIP-related traffic.
Page 153: Overview Of Ospf
OSPF VERVIEW OF OSPF VERVIEW OF OSPF is a link state protocol that distributes routing information between routers belonging to a single IP domain, also known as an autonomous system. In a link state routing protocol, each router maintains a database describing the topology of the autonomous system.
Page 154: Area 0
OUTING ROTOCOLS The three types of routers defined by OSPF are as follows: • Internal Router (IR) An internal router has all of its interfaces within the same area. • Area Border Router (ABR) An ABR has interfaces in multiple areas. It is responsible for exchanging Summary Advertisements with other ABRs.
Page 155: Virtual Links
IRTUAL INKS In the situation when a new area is introduced that does have a direct physical attachment to the backbone, a virtual link is used. A virtual link provides a logical path between the ABR of the disconnected area and the ABR of the backbone. A virtual link must be established between two ABRs that have a common area, with one ABR connected to the backbone.

Page 191: Rmon Features Of The Switch
A typical RMON setup consists of the following two components: • RMON probe — An intelligent, remotely controlled device or software agent that continually collects statistics about a LAN segment or VLAN. The probe transfers the information to a management workstation on request, or when a predefined threshold is crossed.
Page 192: Alarms
RMON requires one probe per LAN segment, and standalone RMON probes have traditionally been expensive. Therefore, Extreme’s approach has been to build an inexpensive RMON probe into the agent of each switch. This allows RMON to be widely deployed around the network without costing more than traditional network management.

• Modify the configuration using a text editor, and later download a copy of the file to the same switch, or to one or more different switches. • Send a copy of the configuration file to Extreme Networks Technical Support for problem-solving purposes.
Page 205: Boot Option Commands
If no parameters are specified, the image is saved to the current image. Reboots the switch at the date and time specified. If you do not specify a reboot time, the reboot happens immediately following the command, and any previously scheduled reboots are cancelled.

Page 207: A Safety Information
MPORTANT Please read the following safety information thoroughly before installing the Summit switch. • Installation and removal of the unit must be carried out by qualified personnel only. • To reduce the risk of fire or electrical shock, install the unit in a temperature- and humidity-controlled indoor area free of conductive contaminants.
Page 208: Power Cord
AFETY NFORMATION • This unit operates under Safety Extra Low Voltage (SELV) conditions according to IEC 950. The conditions are only maintained if the equipment to which it is connected also operates under SELV conditions. • The appliance coupler (the connector to the unit and not the wall plug) must have a configuration for mating with an EN60320/IEC320 appliance inlet.
Page 209: Fuse
• Disconnect power from the unit before opening the fuse holder cover. The unit automatically adjusts to the supply voltage. The fuse is suitable for both 110V A.C. and 220-240V A.C. operation. To change the fuse, release the fuse holder by gently levering a small screwdriver under the fuse holder catch.

Page 213: Troubleshooting
Troubleshooting If you encounter problems when using the switch, this appendix may be helpful. If you have a problem not listed here or in the release notes, contact your local technical support representative. Power LED does not light: Check that the power cable is firmly connected to the device and to the supply outlet.
Page 214 Telnet facility. Check that Telnet access was not disabled for the switch. If you attempt to log in and the maximum number of Telnet sessions are being used, you should receive an error message indicating so.
Page 215 A network problem may be preventing you accessing the device over the network. Try accessing the device through the console port. Check that the community strings configured for the switch and the Network Manager are the same. Check that SNMP access was not disabled for the switch.
Page 216 ROUBLESHOOTING You forget your password and cannot log in: If you are not an administrator, another user having administrator access level can log in, delete your user name, and create a new user name for you, with a new password. Alternatively, another user having administrator access level can log in and initialize the device.
Page 217 VLANs, IP Addresses and default routes: Recall that the switch can have an IP address for each configured VLAN. It is only necessary to have an IP address associated with a VLAN if you intend to manage (telnet, SNMP, ping) through that VLAN.
Page 218 ROUBLESHOOTING The switch keeps aging out endstation entries in the switch Forwarding Database (FDB): Reduce the number of topology changes by disabling STP on those switches that do not use redundant paths. Specify that the endstation entries are static or permanent.
