54 ExtremeWare 7.2e Installation and User Guide
Managing the Switch
Use the
none
option to remove a previously configured access-profile.
• Community strings —The community strings allow a simple method of authentication between the
switch and the remote Network Manager. There are two types of community strings on the switch.
Read community strings provide read-only access to the switch. The default read-only community
string is public. Read-write community strings provide read and write access to the switch. The
default read-write community string is private.
• System contact (optional)—The system contact is a text field that enables you to enter the name of
the person(s) responsible for managing the switch.
• System name —The system name is the name that you have assigned to this switch. The default
name is the model name of the switch (for example, Summit1 switch).
• System location
(optional)—Using the system location field, you can enter an optional location for
this switch.
• Enabling/disabling link up and link down traps (optional)—By default, link up and link down
traps (also called port-up-down traps) are enabled on the switch for all ports. SNMPv1 traps for link
up and link down are not supported; ExtremeWare uses SNMPv2 traps.
You can disable or re-enable the sending of these traps on a per port basis, by using the following
commands:
disable snmp traps port-up-down ports [all | mgmt | <portlist>]
enable snmp traps {port-up-down ports [all | mgmt | <portlist>]}
The mgmt option will only appear on platforms having a management port.
Displaying SNMP Settings
To display the SNMP settings configured on the switch, use the following command:
show management
This command displays the following information:
• Enable/disable state for Telnet, SSH2, SNMP, and web access, along with access profile information
• SNMP community strings
• Authorized SNMP station list
• SNMP MAC-security traps
• Link up/ link down traps enabled on ports
• SNMP trap receiver list
• SNMP trap groups
• RMON polling configuration
• Login statistics
• Enable/disable status of link up and link down traps
• Enable/disable status of MAC-security traps
SNMP Trap Groups
SNMP trap groups allow you to specify which SNMP traps to send to a particular trap receiver. This
functionality was made possible by the underlying support for SNMPv3. Essentially, a number of
predefined filters are associated with a trap receiver, so that only those traps are sent. If you have
