For more information on Ethernet interfaces, see [Ethernet](https://docs.qualcomm.com/bundle/publicresource/topics/80-70015-251/rb3_gen2_ethernet.html). ## Set up SSH connection Source: [https://docs.qualcomm.com/doc/80-70015-26/topic/get_started.html](https://docs.qualcomm.com/doc/80-70015-26/topic/get_started.html) ### About this task To enable SSH and connect to the device, do the following: ### Procedure 1. To enable SSH, perform the steps mentioned in [Use SSH](https://docs.qualcomm.com/bundle/publicresource/topics/80-70015-254/how_to.html#use-ssh). 2. To connect to the device, run the following command: ssh root@Copy to clipboard For example, if the IP address of the device is 10.92.160.222, then run the following command: ssh root@10.92.160.222Copy to clipboard 3. To connect to the SSH shell, enter the following password: oelinux123Copy to clipboard ## Verify preconfigured MAC address Source: [https://docs.qualcomm.com/doc/80-70015-26/topic/get_started.html](https://docs.qualcomm.com/doc/80-70015-26/topic/get_started.html) ### About this task QPS615 is a PCIe switch on RB3 Gen 2 development kit. It does not have an electrically erasable programmable read only memory (EEPROM) to store the MAC address permanently. However, the MAC address is programmed and stored at a persistent path on the device. To verify the preconfigured MAC address, do the following: ### Procedure 1. To verify the configuration of the interface, run the following command. ifconfigCopy to clipboard A sample output is as follows: ifconfig enP1p5s0f0 Link encap:Ethernet HWaddr XX:XX:XX:YY:YY:YY inet addr:169.254.227.235 Bcast:169.254.255.255 Mask:255.255.0.0 inet6 addr: fe80::533c:8ed6:557:3860/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:19 errors:0 dropped:0 overruns:0 frame:0 TX packets:36 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3416 (3.3 KiB) TX bytes:5559 (5.4 KiB) Interrupt:249 Copy to clipboard The MAC address is stored in the config.ini file and is available at /var/persist of the device. 2. To verify whether the config.ini file is available on the device, run the following command: ls /var/persist/Copy to clipboard 3. To verify the content of the config.ini file, run the following command: cat /var/persist/config.iniCopy to clipboard A sample output is as follows: #MAC ID configuration, For Test purpose only MDIOBUSID1: 1: MAC_ID01: XX:XX:XX:YY:YY:YYCopy to clipboard ## Retain and store MAC address Source: [https://docs.qualcomm.com/doc/80-70015-26/topic/get_started.html](https://docs.qualcomm.com/doc/80-70015-26/topic/get_started.html) ### About this task Whenever the device reboots, the MAC address configuration config.ini file in the persistent path /var/persist is retained. However, while upgrading the software build, if the Erase all before download option is selected, then the configuration file is removed from the device. In such cases, the software assigns a random MAC address. To retain the config.ini file and store the MAC address in a location other than /var/persist, do the following: ### Procedure 1. To back up the file to a local path, run the following command: scp root@:/var/persist/config.ini .Copy to clipboard 2. To restore the backed-up file after upgrading the software build, run the following command: scp config.ini root@:/var/persit/Copy to clipboard Note: When prompted for a password, enter `oelinux123` to authenticate the file transfer via the secure copy protocol (SCP). 3. To store the MAC address in a location other than /var/persist, update the EMAC driver software with the new path in the following source code: sources/data-eth/drivers/qps615/src/tc956xmac_main.c ret = kernel_read_file_from_path("/var/persist/config.ini", &data, &size, 1000, READING_POLICY); Copy to clipboard Last Published: Oct 14, 2024 [Previous Topic Overview](https://docs.qualcomm.com/bundle/publicresource/80-70015-26/topics/overview.md) [Next Topic Features](https://docs.qualcomm.com/bundle/publicresource/80-70015-26/topics/features.md)
