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.
