The Catalyst 6000 series and Catalyst 5000 Series LAN switches are powerful, including many usage and maintenance commands. Below are several common commands and simple descriptions.
For all maintenance commands, see the related manual provided with the hardware device.
1. Port Settings
Set port name
Set port name mod_num/port_num [name_string]
Set port priority
Set port level mod_num/port_num noramal | high
Set port Rate
Set port speed mod_num/port_num <10 | 100 | auto>
Set the port transfer type
Set port duplex mod_num/port_num full | half
Check port configuration status
Show port mod_num/port_num
2. network port sc0 settings
Set the logical port sc0 for physical connection in the VLAN
Set interface sc0 vlan_num [ip_address [netmask [broadcast]
3. VLAN settings
Defines the serial number, name, and type of a VLAN.
Set vlan vlan_num [name] [type]
Check VLAN configuration status
Show vlan
4. Trunk Testing
Create a relay on a specific port
Set trunk mod_num/port_num [on | off | desirable | auto] [vlans]
Check the relay configuration status
Show trunk
5. spantree settings
Set the spantree in a vlan
Set spantree enable [vlan]
Set the bridging forwarding latency in a vlan
Set spantree fwddelay delay [vlan]
Set the hello message sending interval in a vlan
Set spantree hello interval [vlan]
Sets the maximum duration of a vlan connection.
Set spantree maxage agingtime [vlan]
Set the bridge path cost for a port
Set spantree portcost mod_num/port_num cost
6. SNMP Protocol Configuration
Configure the SNMP domain string:
Set snmp community read-only | read-write-all community_string
Set a restricted address or domain:
Set snmp trap rcvr_address rcvr_community
Check the SNMP configuration status:
Show snmp
7. IP packet segmentation
Set IP packet segments in the FDDI and Ethernet bridging
Set ip fragmentation {enable | disable}
8. messages about ICMP not arriving
Set ip unreachable {enable | disable}
9. ARP table settings
Create an arp table and set the refresh time of the table
Set arp {ip_addr hw_addr | agingtime}
10 Configuration of layer-3 Switch Module
Telnet ip_address to the layer-3 Switch module.
Rsm> enable
Rsm # show run displays the current configuration file
Rsm # show int vlan id Display vlan status
Rsm # show ip route display route information
Layer-3 Switch vlan configuration:
Rsm # conf t
Rsm (config) # int vlan id
