CLI User Guide

Preface
This guide describes how to use the Command Line Interface (CLI) for the Magnum
6K family of switches. For the Web Management Interface please refer to the Web
Management Guide.
Some simple guidelines which will be useful for configuring and using the Magnum
6K family of switches -
If you need information on a specific command in the CLI, type the
command name after you type the word “help” (help <command> ) or just
type <command> [Enter].
If you need information on a specific feature in Web Management Interface,
use the online help provided in the interface.
If you need further information or data sheets on GarrettCom Magnum 6K
family of switches, refer to the GarrettCom web links at:

telnet is disabled to secure the switch. Do not telnet to the switch to disable telnet. Preferred
method is to do that via the console or using SWM. The client access is not shown here.

FIGURE 102 – Some valid LACP configurations................................................................................195
FIGURE 103 – an incorrect LACP connection scheme for Magnum 6K family of switches. All
LACP trunk ports must be on the same module and cannot span different modules..................195
FIGURE 104 – In this figure, even though the connections are from one module to another, this is
still not a valid configuration (for LACP using 4 ports) as the trunk group belongs to two
different VLANs...................................................................................................................195
FIGURE 105 - In the figure above, there is no common VLAN between the two sets of ports, so
packets from one VLAN to another cannot be forwarded. There should be at least one
VLAN common between the two switches and the LACP port groups. ...................................196
FIGURE 106 – This configuration is similar to the previous configuration, except there is a
common VLAN (VLAN 1) between the two sets of LACP ports. This is a valid
configuration............................................................................................................................197
FIGURE 107 – In the architecture above, using RSTP and LACP allows multiple switches to be
configured together in a meshed redundant link architecture. First define the RSTP
configuration on the switches. Then define the LACP ports. Then finally connect the ports
together to form the meshed redundant link topology as shown above..........................................197
FIGURE 108 – LACP, along with RSTP/STP brings redundancy to the network core or
backbone. Using this reliable core with a dual-homed edge switch brings reliability and
redundancy to the edge of the network.......................................................................................198

FIGURE 119 – IGMP concepts – Isolating multicast traffic in a network.............................................217
FIGURE 120 - In a Layer 2 network, an IGMP multicast traffic goes to all the nodes. In the
figure, T1, a surveillance camera, using multicast, will send the traffic to all the nodes - R1
through R6 - irrespective of whether they want to view the surveillance traffic or not. The
traffic is compounded when additional cameras are added to the network. End result is that
users R1 through R6 see the network as heavily loaded and simple day to day operations
may appear sluggish.................................................................................................................219
FIGURE 121 - Using IGMP-L2 on Magnum 6K family of switches, a Layer 2 network can
minimize multicast traffic as shown above. Each switch has the IGMPL2 turned on.
Each switch can exchange the IGMP query message and respond properly. R4 wants to
view surveillance traffic from T1. As shown by (1), a join request is sent by R4. Once the
join report information is exchanged, only R4 receives the video surveillance traffic, as
shown by (2). No other device on the network gets the video surveillance traffic unless they
issue a join request as well. ......................................................................................................220

1 – Conventions Followed
Conventions followed in the manual…
o best use this document, please review some of the conventions followed in the
manual, including screen captures, interactions and commands with the switch,
etc.
T
Box shows interaction with the switch command line or screen captures from the
switch or computer for clarity
Commands typed by a user will be shown in a different color and this
font
Switch prompt – shown in Bold font, with a “# or >” at the end. For the
document we will use Magnum6K25# as the default prompt.
Syntax rules
Optional entries are shown in [square brackets]
Parameter values within are shown in < pointed brackets >
Optional parameter values are shown again in [square brackets]
Thus
Syntax command [parameter1=<value1>[, parameter2=<value2>]]
parameter3=<value3|value4>
In the example above:
Parameter 1 and Parameter 2 are optional values
Parameter 2 can be used optionally only if Parameter 1 is specified
Parameter 3 is mandatory.
Parameter 1 has value1 = IP address
Parameter 2 has value2 = string
Parameter 3 has value3 or value4
