Using an example, I will configure the Cisco Catalyst 6509-E with firmware 12.2 (33) SXJ7.
And so, connect to the console port, the standard speed is 9600 bps, 8N1.
Example of commands to view information about firmware and hardware:
show module
show inventory
show version
show version | in image
show bootvar
show redundancy
Let’s switch to elevated privilege mode:
enable
An example of viewing the current configuration and saved:
show running-config
show running-config interface GigabitEthernet 1/1
show configuration
Let’s go into configuration mode:
configure t
Specify the name of the device:
hostname Router
Add the user (where admin is any name):
username admin privilege 15 password 7 PASSWORD
Add all vlan:
vlan 207
vlan 226
Configure VLAN interfaces (turn off 1 standard, 207 for management, 226 for users, 192.168.0.1 – DHCP server for L3):
interface Vlan1
no ip address
shutdown
exit
interface Vlan207
ip address 192.168.0.5 255.255.255.0
no shutdown
exit
interface Vlan226
ip address 192.168.20.1 255.255.255.0
no shutdown
ip helper-address 192.168.0.1
no ip redirects
no ip unreachables
exit
If necessary, you can specify a gateway so that the switch can be seen from other networks (on a network 192.168.0.0/24 it can be seen without specifying a gateway):
ip default-gateway 192.168.0.1
You can see which VLAN the device firmware is using with the command:
show vlan internal usage
We will make ACLs with IP addresses from which we will later allow us to connect to SNMP, telnet, etc.:
access-list 10 permit 192.168.0.100
access-list 10 permit 192.168.20.110
show access-list
show ip access-lists
Configure the connection parameters and specify the ACL for telnet:
line con 0
login local
stopbits 1
line vty 0 4
password
login local
access-class 10 in
Configure SNMP (the number 10 indicates the ACL number in which the IP addresses from which you can connect to SNMP are indicated):
snmp-server community public RO 10
snmp-server ifindex persist
snmp-server location "TEXT"
snmp-server contact test@ixnfo.com
snmp-server enable traps tty
snmp ifmib ifindex persist
View SNMP settings:
show snmp
show snmp engineID [local | remote]
show snmp groups
show snmp user
You can disable SNMP and remove community with the following commands:
no snmp-server
no snmp-server community public
Configure the interfaces (ports), as I described in this article:
Configuring ports in Cisco switches
You can enable/disable interfaces with the following commands:
shutdown
no shutdown
Log settings (logging level from 0 to 7, 0 – minimum information):
logging on
logging buffered 0-7
Set up time synchronization with the NTP server:
clock timezone UTC 2
ntp server 192.168.1.1 version 2
exit
show clock
Example of viewing logs, VLAN, packet statistics on ports:
show log
show vlan id 226
show int GigabitEthernet 1/1
show int gigabitEthernet 1/6 counters
View CPU, memory and power supply loading:
show processes
show processes cpu
sh proc cpu sorted 1
show processes cpu sorted | ex 0.00
sh proc cpu hist
show processes memory
show power
show power available
show power used
show int | inc line protocol | packets/sec
Save the configuration:
copy run start
write
By the way, Xenpak to SFP + interface converters are installed in 10Gb slots, I had to remove them and insert them into the hot one, everything is ok, you can remove and insert boards in the same way.
