Dell Networking S-Series: Basic Interface Configuration – SONIC 4.0

Dell Networking S-Series: Basic Interface Configuration - SONIC 4.0

Summary: How to configure SONIC 4.0 interface basics.
Instructions
These steps assume that the switch is being configured starting with factory-default settings as a stand-alone unit. Please see the linked Knowledge Base article for the written examples.
In Native format, SONIC front panel interfaces are named from Ethernet 0 to Ethernet X, with X being the last front panel port.  Standard naming uses the Ethernet x/y/z mode, where x/y are the slot/port #s and z is used for breakout ports.
 Interface Naming Format Change: Changing the default interface naming mode from Native to Standard.  

1. From the Linux prompt, start the SONIC CLI with "sonic-cli":

admin@sonic:~$ sonic-cli
sonic#

 

2. Show the interface status mode currently configured with "show interface-naming"

sonic# show interface-naming
Interface naming mode is native
sonic#

 

3. Show the interface status and see the default interface naming convention (Native naming) "show interface status"(Figure 1):

Figure 1: show interface status example.

4. To modify the switch configuration, run the "configure terminal" command.

sonic# configure terminal
sonic(config)#

 

5. To change the interface naming mode to Standard mode, use the command “interface-naming standard”:

sonic(config)# interface-naming standard
Broadcast message: Interface naming mode has changed. Users running 'sonic-cli' are required to restart your session.
                                                                               
sonic(config)#

 

6. Exit configuration mode with "exit":

sonic(config)# exit
sonic#

 

7. Exit SONIC CLI with “exit”:

sonic# exit
admin@sonic:~$

 

8. Re-enter SONIC CLI with "sonic-cli":

admin@sonic:~$ sonic-cli
sonic#

 

9. Show interface status with "show interface status":

sonic# show interface status

Notice the change in interface names from Ethernet X to Eth x/y(Figure 2).

Figure 2: Standard mode: show interface status example

10. Save the running configuration to startup configuration with "write memory":

sonic# write memory
sonic#

Individual interface configuration: Enter configuration mode, then enter the interface configuration mode.

1. Start SONiC CLI with "sonic-cli":

admin@sonic:~$ sonic-cli
sonic#

 

2. Show the interface configuration with "show running-configuration interface Eth 1/30":

sonic# show running-configuration interface Eth 1/30
!
interface Eth1/30
 mtu 9100
 speed 25000
 fec none
 shutdown

 

3. Enter configuration mode with "configure terminal":

sonic# configure terminal
sonic(config)#

 

4. Enter interface Eth 1/30 configuration mode with "interface Eth 1/30":

sonic(config)# interface Eth 1/30
sonic(conf-if-Eth1/30)#

 

5. No shut interface Eth 1/30 with "no shutdown":

sonic(conf-if-Eth1/30)# no shutdown
sonic(conf-if-Eth1/30)#

 

6. Configure an IP address on interface Eth 1/30 with “IP address 10.1.1.2/24”:

sonic(conf-if-Eth1/30)# ip address 10.1.1.2/24
sonic(conf-if-Eth1/30)#

 

7. Exit configuration mode with "end":

sonic(conf-if-Eth1/30)# end
sonic#

 

8. Show the interface configuration with "show running-configuration interface Eth 1/30":

sonic# show running-configuration interface eth 1/30
!
interface Eth1/30
 mtu 9100
 speed 25000
 fec none
 no shutdown
 ip address 10.1.1.2/24

 

9. Show IP interfaces with "show ip interfaces":

sonic# show ip interfaces
Flags: U-Unnumbered interface, A-Anycast IP
-----------------------------------------------------------------------------------------------
Interface            IP address/mask                    VRF            Admin/Oper     Flags         
-----------------------------------------------------------------------------------------------
Eth1/30              10.1.1.2/24                                           up/up                        
sonic#

 

10. Show interface status for Eth 1/30 "show interface eth 1/30":

(output truncated for brevity)

sonic# show interface eth 1/30
    
Eth1/30 is up, line protocol is up
Hardware is Eth
IPV4 address is 10.1.1.2/24
Mode of IPV4 address assignment: MANUAL
Mode of IPV6 address assignment: not-set
Interface IPv6 oper status: Disabled
IP MTU 9100 bytes
LineSpeed 25GB, Auto-negotiation off
FEC: DISABLED
Last clearing of "show interface" counters: never
…

 

11. Save the running configuration to startup configuration with "write memory":

sonic# write memory
sonic#

Mutliple Interface Configuration: To configure multiple interfaces simultaneously, use the 'interface range' option. To view a range of interfaces with a show command, the ‘range’ keyword is not needed.
Example:

• To configure consecutive range of ports 14 through 15 would be "interface range ethernet 1/1/14-1/1/15".
• To configure nonconsecutive range of ports 3,10,19 would be "interface range ethernet 3,10,19".
• To configure a mix of consecutive and nonconsecutive would be "interface range ethernet 1/1/3, 1/1/14-1/1/15".

1. To show multiple interfaces, the 'range' option is not necessary. To show Ethernet 1/1-1/3,1/5 use the command "show interface Eth 1/1-1/3,1/5":

(output truncated for brevity)
sonic# show interface Eth 1/1-1/3,1/5
    
Eth1/1 is down, line protocol is down, reason admin-down
Hardware is Eth, address is 0c:02:22:c7:00:08
Mode of IPV4 address assignment: not-set
...
Output statistics:
        0 packets, 0 octets
        0 Multicasts, 0 Broadcasts, 0 Unicasts
        0 error, 0 discarded, 0 Oversize
    
Eth1/2 is down, line protocol is down, reason admin-down
Hardware is Eth, address is 0c:02:22:c7:00:08
Mode of IPV4 address assignment: not-set
...
Output statistics:
        0 packets, 0 octets
        0 Multicasts, 0 Broadcasts, 0 Unicasts
        0 error, 0 discarded, 0 Oversize

Hardware is Eth, address is 0c:02:22:c7:00:08
Mode of IPV4 address assignment: not-set
...
Output statistics:
        0 packets, 0 octets
        0 Multicasts, 0 Broadcasts, 0 Unicasts
        0 error, 0 discarded, 0 Oversize
    
Eth1/5 is down, line protocol is down, reason admin-down
Hardware is Eth, address is 0c:02:22:c7:00:08
Mode of IPV4 address assignment: not-set
...
Output statistics:
        0 packets, 0 octets
        0 Multicasts, 0 Broadcasts, 0 Unicasts
        0 error, 0 discarded, 0 Oversize
sonic(config)# end

 

2. Run the "configure terminal" command.

sonic# configure terminal
sonic(config)#

 

3. Configure interfaces Ethernet 1/1-1/3,1/5,/1/7-1/9 using “interface range Eth1/1-1/3,1/5,1/7-1/9”:

sonic(config)# interface range eth 1/1-1/3,1/5,1/7-1/9
%Info: Configuring only existing interfaces in range
sonic(conf-if-range-eth**)#

 

4. Configure interfaces no shut with “no shut”:

sonic(conf-if-range-eth**)# no shutdown
sonic(conf-if-range-eth**)#

 

5. Configure interfaces for access mode vlan 1 with "switchport access vlan 1":

sonic(conf-if-range-eth**)# switchport access vlan 1
sonic(conf-if-range-eth**)#

 

6. Verify the user configuration using "show interface status"(Figure 3):

 
Figure 3: Show interface status example

7. Check VLAN 1 interface assignments with "show vlan 1" (Figure 4):

Figure 4: Show vlan 1 example 

8. Save the running configuration to startup configuration with "write memory":

sonic# write memory
sonic#
