I have the CRS326-24G-2S+RM, upgraded it to the 7.12 version and set it up according to my simple configuration (Ip address/Routes/DHCP and some simple firewall rules).
I imported into firewalls/address-lists a large blacklist resulting to leaving the machine with 0 bytes of flash memory.
I deleted all the adress lists and rebooted the machine but still the adress lists exist in the flash memory, like theyre not being deleted at all.
After that I reset the configuration but the machine seems to not be reset at all. I cant create a new configuration neither change some settings in it because when the
machine reboots the configuration is lost.
When flash is almost full, it’s not possible to remove part of config (it seems that ROS wants to save a copy of new config before deleting old and it fails to do so). So this situation is unrecoverable, netinstall is the only way out. After netinstall, don’t add large address lists on devices with tiny flash.
Besides, CRS devices are mainly switches, so extensive address lists don’t really belong on these devices.
I don’t think you can. And even if it’s possible, this doesn’t guarantee to really get vanilla setup, sometimes some settings escape all the reset hooks. Netinstall is the only way where reset is guaranteed (it formats flash and installs ROS from scratch).
