class_map

Class map manipulation.

This module provides access to the management of class maps. Classification or “class” maps, provide a way for the network operator to classify packets arriving on an interface. Together with the policy_map_mgr in policy_map.h, classified traffic can drive policy features, such as PBR.

namespace eos

class class_map_iter_t

#include <class_map.h>

An iterator providing forwards only iteration over collections of class maps.

Private Functions

class_map_iter_t(class_map_iter_impl * const)

Friends

friend class class_map_iter_impl

class class_map_mgr

#include <class_map.h>

EOS class map manager.

This manager provides access to EOS traffic classifiers, or “class maps”. Class maps are referred to by policy maps (policy_map.h) to classify traffic that should be subject to the policy’s actions.

Public Functions

virtual ~class_map_mgr()

virtual void resync_init() = 0

Resync mediates class map configuration into a known good state.

To start a resync, call resync_init() and then use the functions in the module to manipulate class maps like normal, setting them with class_map_is(). After all entries have been set, call resync_complete(), which will delete existing class_maps that were not added or modified during resync.

During resync, this manager will act like it is referencing a temporary table that starts off empty. Thus, methods like exist, del, and getters will act only on that temporary table, regardless of the real values in Sysdb. The one exception is iteration; they will traverse the table stored in Sysdb, regardless of whether or not the manager is in resync mode.

virtual void resync_complete() = 0

Completes any underway resync operation.

virtual bool exists(class_map_key_t const & key) const = 0

Returns true if and only if the provided key exists in the system config.

virtual class_map_t class_map(class_map_key_t const & key) const = 0

Returns the class map for the provided class map key. If there is no class map for the key, returns a default class_map_t

virtual void class_map_is(class_map_t const & class_map) = 0

Sets a class map and commits its configuration.

virtual class_map_iter_t class_map_iter(policy_feature_t) const = 0

Provides iteration over the configured class maps for a feature.

virtual void class_map_del(class_map_key_t const & key) = 0

Deletes the class map specified.
