It can be passed into get_interface_dict() if explicitly required - else it is taken from the environment. --- python/vyos/configdict.py | 11 ++++++++--- src/conf_mode/interfaces-bonding.py | 10 ++-------- src/conf_mode/interfaces-bridge.py | 11 ++--------- src/conf_mode/interfaces-dummy.py | 8 +------- src/conf_mode/interfaces-ethernet.py | 8 +------- src/conf_mode/interfaces-geneve.py | 9 +-------- src/conf_mode/interfaces-loopback.py | 8 +------- src/conf_mode/interfaces-macsec.py | 8 +------- src/conf_mode/interfaces-pppoe.py | 8 +------- src/conf_mode/interfaces-pseudo-ethernet.py | 8 +------- src/conf_mode/interfaces-wireless.py | 8 +------- src/conf_mode/interfaces-wirelessmodem.py | 9 +-------- 12 files changed, 21 insertions(+), 85 deletions(-) (limited to 'src/conf_mode/interfaces-wireless.py') diff --git a/python/vyos/configdict.py b/python/vyos/configdict.py index 53b5f9492..126d6195a 100644 --- a/python/vyos/configdict.py +++ b/python/vyos/configdict.py @@ -15,8 +15,8 @@ """ A library for retrieving value dicts from VyOS configs in a declarative fashion. - """ +import os import jmespath from enum import Enum @@ -24,7 +24,6 @@ from copy import deepcopy from vyos import ConfigError from vyos.validate import is_member -from vyos.util import ifname_from_config def retrieve_config(path_hash, base_path, config): """ @@ -195,7 +194,7 @@ def get_removed_vlans(conf, dict): return dict -def get_interface_dict(config, base, ifname): +def get_interface_dict(config, base, ifname=''): """ Common utility function to retrieve and mandgle the interfaces available in CLI configuration.
