Setting up a cat5000

1. Initial Setup

Note that the switch comes out of the box with no telnet configed. All settings must be manualy done throught the serial cable which is a standard Cat5 Patch cable connected to a DB9-RJ45 converter which attaches to your computer.
  1. Set Switch IP Configuration
  2. Set Switch Ports
  3. Set VLAN Trunk Protocol

1.1 Set Switch IP Configuration

Here we just setup the basic configuration so the switch can be telneted into.
  • set interface sc0 ip_addr netmask
    Set the management interface sc0 to have a specific ip and netmask
  • set interface sc0 vlan_num
    Set the managament intercface sc0, to a specific vlan. Note, this will not work unless you have already setup the VLAN's. If you have not, you can wait and do this later.
  • set ip route default gateway
    This just sets the default gateway, but the command can be modified by removing the "default" command so that it can route to specific networks.
  • show interface
  • show ip route
    These two commands shows the settings that were just set.

1.2 Set Switch Ports

This is just the basic port configs, not including setting up VLAN's.
  • set port speed mod_num/port_num {10 | 100 | auto}
    To set the speed of the port. Staticly assigning speeds up a ports initial time it takes to setup the port.
  • set port duplex mod_num/port_num {full | half}
    To set the duplex mode. Note that this must be set the same on both sides.
  • set port flowcontrol mod_num/port_num {recieve | send} {on | off | desired}
    On Fast E or Gig E ports, set the flow control mode for transet and recieve ports, and set the config link negotiation.
  • set port name mod_num/port_num name_string
    You can set the name for each port
  • show port mod_num/port_num

1.3 Set VLAN Trunk Protocol

For configuring the Switch as a VTP Server:
  • set vtp domain name
  • set vtp mode server
  • show vtp domain

2. Working with VLANS

  1. Create VLANs
  2. Assign Switch Ports to VLANs
  3. Configure VLAN Trunks

2.1 Create VLANs

  • set vlan vlan_num [name name]
  • show vlan vlan_num

2.2 Assign Switch Ports to VLANs

  • set vlan vlan_num mod_num/port_num
  • show vlan vlan_num
  • show port [mod_num/port_num]

2.3 Configure VLAN Trunks

  • show port capabilities [mod_num[/port_num]]
  • set trunk mod_num/port_num {on | desirable | auto} {isl | dot1q | negotiate}
  • show trunk

3. Administering the Switch

This is layed out below the section "2. Working with VLAN's" because some of these steps involve having setup the vlans first.
  1. Global System Settings
  2. Manage the Configs

3.1 Global System Settings

  • set system name name_string
  • set system location location_string
  • set system contact contact_string
  • set time mm/dd/yy hh:mm:ss
  • set prompt prompt_string
  • set password
  • set enablepass

  • set banner motd c [text] c
    Where c is a character string that signifies the begining and ending of the message

3.2 Manage the Configs

  • show config
  • copy config tftp
  • write network

  • copy tftp config
  • configure network

4. Monitoring the Switch

  1. General
  2. Ports
  3. Network

4.1 General

  • show system
  • show module [mod_num]

4.2 Ports

  • show port [mod_num[/port_num]]
  • show port capabilities [mod_num[/port_num]]

4.3 Network

  • ping [-s] host [packet_size] [packet_count]
  • traceroute [-q nqueries ] data_size
  • show interface
  • show ip route

5. Setting Up Sysloging

pepe> (enable) set logging server added to System logging server table.

pepe> (enable) set logging server facility local3
System logging server facility set to 

pepe> (enable) set logging server severity 5
System logging server severity set to <5>

pepe> (enable) set logging server enable
System logging messages will be sent to the configured syslog servers.

pepe> (enable) sh logging

Logging buffer size:          500
        timestamp option:     enabled
Logging history size:         1
Logging console:              enabled
Logging server:               enabled
        server facility:      LOCAL3
        server severity:      notifications(5)
Current Logging Session:      enabled
