Primary port is the port over which specific traffic like Multicast IGMP , unknown Unicast and broadcast traffic is transmitted. As shown by the add port command, the port with the lowest priority value has the highest priority and is designated as the primary port.

In the figure shown above, Switch 1 has ports 11 and 15 forming the first trunk, connecting to Switch 3. Switch 1 also has ports 17 and 23 forming the second trunk on Switch 2. To make the preemptive queuing possible, most switches implement at least two queue buffers. The Magnum 6K family of switches has two priority queues, 1 low and 0 high.

DiffServ works by tagging each packet at the originating device or an intermediate switch for the requested level of service it requires across the network. You can partition traffic in up to eight classes of service using IP precedence. QoS is disabled by default on the switch. QoS needs to be enabled and configured. Once the weight is set, all the ports will be the same weight across the switch.

The valid value for weight is A weight is a number calculated from the IP precedence setting for a packet. For example, when a packet is received untagged and has to be transmitted with an addition of the The valid value for weight is Syntax show-portweight - display the weight settings on a port It is used to establish host memberships in particular multicast groups on a single network. The mechanisms of the protocol allows a host to inform its local router, using Host Membership Reports that it wants to receive messages addressed to a specific multicast group.

The multicast group running version 2 of IGMP uses three fundamental types of messages to communicate: A message sent from the querier multicast router or switch asking for a response from each host belonging to the multicast group.

If a multicast router supporting IGMP is not present, then the switch must assume this function in order to elicit group membership information from the hosts on the network.

The routers operate as queriers. In this case, the IGMP-configured switch runs as a querier. PCs 2, 5, and 6 are members of the same IP multicast group. IGMP is configured on switches 3 and 4. Either of these switches can operate as querier because a multicast router is not present on the network.

The benefits of IGMP are clear. It disables the port where the leave message is received ability to transmit multicast traffic. Querier shows where the switch is acting a querier or a non-querier. In the example above the switch is the querier. Querier Interval shows the time period in seconds on which the switch sends general host- query messages. Timer shows the amount of time left in seconds before the group port will be deleted or will not be able to route multicast traffic if the switch does not receive a membership report.

Leave Pending column shows the number of leave messages received from this port Every port can be individually set to three different IGMP modes — These messages are sent to ask for group membership information.

This is sent to the all- system multicast group address, The default is enabled There are many software packages which provide a graphical interface and a graphical view of the network and its devices. The graphical interface and view would not be possible without SNMP. This is done to protect the switch from being polled by unauthorized managers.

Valid for SNMP v1. The following RMON groups are supported: Valid for SNMP v. Maximum of five stations allowed. An inform notification is an acknowledgments that a trap has been received. A user can add up to 5 stations. These items are examined individually in this chapter. Alarm Relays In a wiring closet, it would be helpful if there was a visual indication for faults on components on the network. This may be needed to adjust to the behavior of the circuit or relay.

Default is 3 seconds. If this capability is used, please ensure that SPAM filters and other filters are not set to delete these emails. If value is none, no traps are sent to this recipient. When using the serial connectivity with applications such as Hyper terminal etc.

The important parameters to set for any serial connectivity software is to set the line delay to be milliseconds and the character delay to be 50 milliseconds. Syntax show history — show the last 25 commands executed — if less than 25 commands are executed, only those commands executed are shown If the user logs out or if the switch times out — the history is erased. No Parity Stop Flow Control: None show history Magnum6K25 1: The event log window contains 22 log entry lines.

Also notice that there are other MAC addresses associated with port 3, indicating that the port has a hub or a switch connected to it. MNS-6K allows a maximum of 5 recipients email — The prompt has predefined variables. This is useful to specify whether a log file or host file is uploaded or downloaded. The default is enabled adds or deletes a management station, specified by the IP address, which can query SNMP variables from the switch.

Applicable for SNM v1 only. Description configure port mirror settings configure port security settings specifies the port or switch level priority. If no ports are specified, then the switch bridge priority is specified and its value is specifies the port or switch level priority.

Note as discussed earlier, you can create multiple RS-rings on a switch remove the switch from RS-Ring topology by eliminating the end ports on the switch enter the RSTP configuration mode enable RSTP — by default, this is disabled and SNMP to v1 only. Need to save and reboot the switch after this command sets the time as well as the timezone. Default value is 10 seconds. The Range can be from 2 to seconds.

Restrictions apply to the maximum value because of an internal calculation that is dependent on the value of the Query Interval. The valid value for weight is displays which mac address is associated with Description display the hosts table entries IGMP operation status display all trusted hosts shows the IP parameters set in the switch displays the status and other relevant LACP information display the status of LLL display logs and specific types of logs For assigning access capabilities to the user — for example to allow or not allow telnet access to the switch a part of the View based Access control model VACM as defined in RFC This command defines a manager or group or manager stations what it can access inside the MIB object tree.

In addition to the value "none" no time changes , there are fifteen pre- defined settings, a few examples are: The first step is to ensure that you have the proper version of the MNS-6K software. To access the proper software, you will require access to the GarrettCom web site and ftp site through a network which does not block ftp file transfers.

If your site blocks ftp file transfer traffic, please contact your system administrator to figure out how to access the GarrettCom site to download the necessary software. Intentionally left blank for image continuity — image shown on next page ftp: There are other folders with additional software, MIBs as well as additional useful information for the Magnum-6K switches which you may want to use later.

The access can be over the console port using the null modem cable or through the network using telnet. This is described in step 2. Preparing to load the software Backup your existing configuration…..

This section will show you how to save the existing configuration and prepare you for loading the configuration. Magnum 6K switch or DNS name associated with the switch to be upgraded. Access the Magnum 6K switch by using the telnet command.

For example, if the switch has the IP address For ftp services, make sure the server can support anonymous login or make sure the login password information is available. This is described in step 3. This is described in step 4. To use the serial connection to update the MNS-6K image, the command dialog is shown below: Ensure that the server has access to the MNS-6K software image downloaded in step 2. The switch will now reboot. Verify the MNS-6K software was upgraded.

Note — as discussed in step 1, the switch may need a boot code update. Magnum 6K switch and finally, if required, the configuration can be restored using the instructions in this step. If the Magnum 6K switch is updated over the network, it maybe necessary to update the boot code.

At boot up time, the Magnum 6K switch identifies that there is a new version of the boot code and asks if the new boot code should be loaded If the boot code does not load properly, please contact GarrettCom Inc technical support at , email — support garrettcom.

They were first described by Karl Landsteiner and Philip Levine in Anti-M and anti-N antibodies are usually IgM and are rarely associated with transfusion reactions.

Anti-N is sometimes seen in dialysis patients due to cross-reactions with the residual formaldehyde from sterilizing the equipment. This is usually irrelevant for transfusion since this variant of the antibody does not react at body temperature. Anti-S and anti-s can cause hemolytic transfusion reactions and hemolytic disease of the newborn. The U antigen is a high incidence antigen, occurring in more than The U was originally short for "Universal", though this is not the case.

U negative RBCs can be found in people of African descent. This mutation in red cell surface structure also makes the RBCs S- and s-.
