102 IGMP Theory of Operation The following three topologies detai l how IGMP Query works and to be configured within a network: 1. Auto mode needs to be enabled when the router’s IP address is smaller than other switches in t h e s u bn et.
103 2. IGMP needs to be enabled when the router’s IP address is not smaller than other switches in the sub net. This Router supports IGMP protocol, but IGMP has to be enabl ed, and the Router has to be the Querier.
104 3. The following topology must be set when the IP address of the s witch is not the smallest in the subnet. T he network will cause a mu lti-ca st st orm from the IGMP client report if it is in Auto mo de. All switches must be in disable mode when the VOD server is configured for IGMP Querier.
105 5-4-3. Console Port Informatio n Console is a standa rd UAR T inte rface to commu ni cate with a serial port. The Windows HyperTerminal program can be used to li nk the switch with the console port. In order to change any of these parameters, you must be connected to the console port.
106 5-4-4. Port Controls The menu allows changing of port configurat ions. State: User can disable or enable each port. Negotiation: User can set auto negotiation mode for each port to Auto, Nway (specify the speed/dupl ex on this port and en able aut o- negot iation) or Force.
107 1 to 1000: valid rate value. Priority: This st at i c prior i t y is bas ed on eac h port sett ing. If the port priori ty is set high, incoming frames from this port will always be high priority frames. Security: A port in securit y mode will be “l ocked” unless addre ss learning is enabled.
108 5-4-5. Trunking The Link Aggregation Co ntrol Protocol (LACP) provides a standardized means f or exchan gi ng inform at i o n bet w een Part ner Syst ems on a link to allow their Link Aggregati on Control instances.
109 5-4-5-1. Aggregator Setting System Prior i ty: A value used to id entify the active LACP . The switch with the lowest value has the hi ghest pri o r it y and is s elected as the ac t ive LACP. To create a trunk across two or more ports: 1. Group ID: Choose the "G roup ID " and click "Get".
110 configure LACP Acti ve/Passive status for each port. 5. Click the Apply button to save the new configuration. 6. To re m ove ports f rom a trunk gr o up, highlight the port s in the table you want to remove and then click the Remove butto n.
111 5-4-5-2. Aggregator Inf orm atio n The LACP Aggregator relation inform ation is displayed as shown..
112 5-4-5-3. State Activity Active ( select ed) : The active p ort automatica lly sends LACP protocol packets. Passive (not selected) : The passive port does not automatically send LACP protocol packets, but respon ds only if it receives LA CP protocol packets from the other device.
113 status will be created automatically..
114 5-4-6. Forwarding and Filterin g 5-4-6-1. IGMP Snooping The switch supports IP multicasting. You can enable IGMP via the web management’s configuratio n screen. I n addition, you can view different multicast groups, VIDs and member port s, and IP multicas t addresses that range from 224.
115 IGMP has three fundamen tal types of messages: Message Description Query A message sent from the querier (IGMP router or switch) asking for a response from each host belonging to the multicast group.
116 5-4-6-2. Static MAC Address When a static MAC address is added, it remains in the switch's address table, regardless of whether or no t the device is physically connected to the switch. This saves the switch from having to re-learn a de vi ce's MAC address when the device is disconne cted or power ed- of f.
117 addresses are associated wi th indiv id ual VLA N s . Type the V I D ( t ag-based VLANs) to associate wi th the MAC address. 6. Click the Add button. 7. To delete a stat ic MAC address, hi ghlight the selectio n in the table you want to delete and then click the Delete button.

124 Security VLANs Security VLAN ’s allow for limitin g teln et, SNMP and web acce ss to the switch to a specific VLAN. The VID of th e Security VL AN m a y be c hanged from 255 to another value after creating the VLAN . The new VID must not already exist on the box.
125 Basic T o create a VLAN and add t agged memb er port s to it: 1. Select the Add button to creat e a new VLAN. 2. Enter a nam e for t he new V L AN. 3. En ter a VLAN ID (2 to 4094). The default is 1. 4. Choose the protocol type. Default i s NONE. 5.
126 Tag: Outgoing fram es wit h VLAN-Tagged. Untag: Outgoing fram es without VLAN-Tagged..
127 VLAN Port ID To configure port VID settings: From the main 802.1Q VLAN page , click Port VLAN ID Se ttings. VLAN ID Set the port VLAN ID that will be assigned to untagged traffic on a given port. This feature is useful for accommodat ing devices that you wa nt to particip ate in the VLAN but that do n’t support tagging.
128 the port belongs to that VLAN. Enable : Forward only packets wi th VID ma tching this por t's configured VID. Disable : Disable Ingress filter function. Acceptable Frame Type ALL: All packets are acceptabl e. Ta g O n l y : Only packet s t hat match the VLAN ID will hav e perm ission t o go through the port.
129 5-4-8. Spanning Tree The Spanning-Tree Protocol (STP) is a standardiz e d method (IEEE 802.1d) for avoiding loops in switched networks. When ST P is enabled it ensures that only one path at a time is active between any tw o nodes on the network.
130 5-4-8-1. System Configuration To enable STP mode select the box next to STP State and click so that a check mar k √ appears. This indicates that ST P is enabled on the device. After enabling STP, configure the syst em level functions for the device.
