I’ve ran into an instance where I need to adjust the MTU on a PFC200 interface, however I’m running into an issue with persistence.
I was given an initial procedure (thanks @tyrone.visser ), however it seems on FW22, the
/etc/network/interfaces file is only used for the loopback.
# Network configuration is handled by netconfd. # ifup/ifdown are only used for loopback device, currently. auto lo iface lo inet loopback
When the required line to adjust the size of the MTU is added:
post-up /sbin/ifconfig br0 mtu 1380 up
the MTU hasn’t changed after reboot. A query using
ifconfig br0 shows an unchanged MTU.
Also, I’ve tried looking into this on another PFC200 with FW25, but even though FW25 is still using Linux distro PTXdist, it has no
/etc/network/ folder at all.
Does anyone have any ideas?
