Configures the MTU (maximum transmission unit) at the physical port level for Layer 2, IPv4, and IPv6.
In SLX-OS, you can use the show interface ethernet command to see the MTU configuration for an interface.
This example configures the MTU on one device.
efa inventory device interface set-mtu --ip 10.25.225.167 --if-name 0/20-22 --mtu 2000 --ip-mtu 2000 --ipv6-mtu 3000 +---------------+----+------+----------------+------+--------+----------+--------- | DeviceIP | ID | Name | Interface Type | MTU | IP MTU | IPv6 MTU | Result +---------------+----+------+----------------+------+--------+----------+--------- | 10.25.225.167 | 1 | 0/22 | ethernet | 2000 | 2000 | 3000 | Success + +----+------+----------------+------+--------+----------+--------- | | 9 | 0/21 | ethernet | 2000 | 2000 | 3000 | Success + +----+------+----------------+------+--------+----------+--------- | | 89 | 0/20 | ethernet | 2000 | 2000 | 3000 | Success +---------------+----+------+----------------+------+--------+----------+--------- Interface MTU Details --- Time Elapsed: 18.6886395s ---
This example attempts to configure the MTU for two IP addresses, however one IP address is invalid.
efa inventory device interface set-mtu --ip 10.25.225.167,10.10.10.10 --if-name 0/20-22 --mtu 2500 --ip-mtu 2500 --ipv6-mtu 2500 ---------------+----+------+----------------+------+--------+-----------------+------ | DeviceIP | ID | Name | Interface Type | MTU | IP MTU | IPv6 MTU |Result +---------------+----+------+----------------+------+--------+----------------+------ | 10.10.10.10 | | | | | Failed | Device does not | | | | | | | exist with IP: 10.10.10.10 +---------------+----+------+----------------+------+--------+----------------+------- | 10.25.225.167 | 89 | 0/20 | ethernet | 2500 | 2500 | 2500 |Success + +----+------+----------------+------+--------+----------------+------- | | 1 | 0/22 | ethernet | 2500 | 2500 | 2500 |Success + +----+------+----------------+------+--------+----------------+------- | | 9 | 0/21 | ethernet | 2500 | 2500 | 2500 |Success +---------------+----+------+----------------+------+--------+----------------+------- Interface MTU Details --- Time Elapsed: 18.6252821s ---
This example configures the MTU on multiple IP addresses.
