Firmware Version: ER605(UN)_V2.20_2.3.1 Build 20251015

Hi All,

 

Using Linux to do the SNMP walk for ER605, however, I am unable to fetch all the interface.

 

It seems like there is a limitation by the firmware / hardware.

 

:~$ snmpwalk -v2c -c public 192.168.1.1 | grep eth


iso.3.6.1.2.1.2.2.1.2.1026 = STRING: "default/eth0"
iso.3.6.1.2.1.2.2.1.2.1027 = STRING: "default/eth1"
iso.3.6.1.2.1.2.2.1.2.1034 = STRING: "default/veth0"
iso.3.6.1.2.1.2.2.1.2.1035 = STRING: "default/veth1"
iso.3.6.1.2.1.31.1.1.1.1.1026 = STRING: "default/eth0"
iso.3.6.1.2.1.31.1.1.1.1.1027 = STRING: "default/eth1"
iso.3.6.1.2.1.31.1.1.1.1.1034 = STRING: "default/veth0"
iso.3.6.1.2.1.31.1.1.1.1.1035 = STRING: "default/veth1"

You're only seeing four logical interfaces (eth0, eth1, veth0, veth1) because the ER605 (TL-R605) V2 firmware does not expose the individual LAN/WAN ports via SNMP. Instead, it aggregates them into internal virtual interfaces (default/ethX) and hides the switch-port details from standard MIB-2 tables like ifTable and ifXTable.This is by design, not a misconfiguration on your side.
