Changelogs

Fix

• iosxe

  • Updated the shared single-RP and dual-RP syntax transition to use config check syntax so syntax checking works consistently on IOS XE and CAT9k HA devices.

  • Updated configure(config_syntax_check=True) and config_syntax() to enter syntax-check mode, validate the supplied commands, and return to enable mode.

  • Removed the obsolete syntax_configlet handling and unregistered Syntaxsh service.

  • Modified state machine

    • Answer the uncommitted changes prompt when leaving configuration mode on controller-managed single- and dual-RP devices.

  • Updated CAT8K reload-to-ROMMON handling to recognize System Bootstrap output.

  • Saves the environment when prompted and sends Ctrl-C at the boot interruption point.

  • Added the C8300-2N2S-4T2X PID mapping for CAT8K C8300 plugin selection.

  • Fixed ROMMON boot dialogs to invoke wrapped statement callbacks according to their declared parameters.

  • Copied generic connection statements before applying IOS XE-specific callback wrapping.

  • Updated the configure service to automatically answer the interactive RSA key modulus prompt with 2048 bits while allowing a caller-provided reply to override the default.

  • Added regression and mock-device coverage to verify RSA key generation completes without a caller-provided dialog.

• iosxe/stack

  • Modified init_standby

    • Added STACK_STANDBY_CONSOLE_ATTACH setting, off by default. Enable it on stacks where every console connects to the active RP.

    • Verify which console is on the standby RP using the ‘*’ row of ‘show switch’ instead of assuming the designated standby handle.

    • Attach to the standby RP console when no console reaches it, so device.standby, target=’standby’ and swap_roles() no longer operate on the active RP without reporting an error.

    • Release a console attach left over from an earlier run before probing, so a stale attach is not mistaken for a real standby.

  • Modified disconnect

    • Detach the standby RP console so the next connect is not refused with ‘Address already in use’.

  • Modified set_init_commands

    • Skip ‘show version’ on an attached standby console, whose output is rate limited and times out the connect.

  • Added stack-specific reload handling for the transition from Press RETURN to an authentication prompt. The stack reload dialog now avoids an empty username and completes authentication in the same dialog flow.

• generic

  • Updated the syslog message pattern to match UNIX ERR:tcgetattr:Inappropriate ioctl for device output so it is handled as ignorable syslog noise.

  • Modified connection_refused_handler

    • Propagate a typed ConnectionRefusedError to Unicon core instead of clearing terminal lines and reconnecting recursively from a connection dialog callback.

    • Removed the plugin-owned CONNECTION_REFUSED_MAX_COUNT default; it is now defined alongside the retry logic in Unicon core.
