What is EPG?

EPG (electronic program guide) is a non-interactive menu of broadcasting scheduling information. It is transmitted on dedicated channels by cable and satellite TV providers and displayed by specialized set-top boxes for viewers.

An EPG is a flexible container for endpoints that share common Policies and allows forwarding to be treated as a group rather than individually. For example, a bridge domain with two subnets could have an EPG configured with intra-EPG isolation enforced.


An EPG is a non-interactive menu of broadcast programming or scheduling information displayed by a television or radio station. These menus are usually broadcast through dedicated channels and contain information for a number of days or weeks.

An IPG is a more modern version of the EPG that allows viewers to browse, select and watch content on multiple channels and video-on-demand services. The IPG also provides information about programs that are currently playing and those that will be available in the future.

In networking, an EPG is a group of management endpoints that share common policies. These groups are logically separated by VLANs, rather than physical locations or addressing. EPGs can be configured statically or dynamically by an APIC and are deployed on ports with the vlanScope set to portlocal. This allows a single EPG to be deployed on multiple leaf switches. This increases network efficiency and improves security by limiting the exposure of sensitive endpoints to malicious actors.


A EPG is a formal document that gives another person authority to make decisions on your behalf if you are unable to do so yourself. It may be useful if you have a medical condition or a mental health condition, such as dementia or Alzheimer’s disease.

A more advanced form of this technology is the interactive television programming guide (IPG). An IPG allows a viewer or listener to navigate scheduling information menus without the need for centralized schedule data from a central server.

The EPG electronic circuit detects tongue-hard palate contact during speech and transfers a signal to the computer through Bluetooth communication. The signals are displayed and analyzed in real-time by the computer, providing feedback to users and speech therapists. The circuit consists of a microcontroller, silver electrodes, a capacitor, and a MHz crystal oscillator. The circuit’s analog signals are converted to digital data by the microcontroller. It then transfers the data to a display screen for evaluation.


An EPG is a non-interactive menu of program scheduling information shown on television and radio by cable and satellite providers to their subscribers. It allows the viewer to select programs for viewing at a later time through a remote control or device. It is a precursor to an Interactive (IPG) which has eclipsed the non-interactive EPG and allows the viewer to select, watch and switch between multiple channels and video-on-demand services.

An endpoint is a management device such as servers, virtual machines, network-attached storage or clients on the Internet. Endpoints have an address, location and attributes (such as version or patch level) that enables the network fabric to determine its identity. An EPG is a group of endpoints that share common policy requirements such as security, virtual machine mobility or QoS. EPGs connect with one another through policy constructs known as contracts.

For example, a contract with a scope of application-profile allows app and db EPGs to communicate only within the application-profile. This avoids the need to have separate sEPG and dEPG policies on each server.


There are many misconceptions about epg. For example, some people assume that if a network uses two identical modes (mc2xml and TitanTV) for different types of channels (CableCARD channels and ATSC OTA channels), then both can share the same epg source. However, this is not the case and it is better to use a separate epg mode for each type of channel.

Some users also confuse contract inheritance with filter settings. In actuality, the two functions are quite different. In a nutshell, contract inheritance allows an EPG to inherit the contract-relation configurations of other EPGs that it references.

This functionality works only when the EPGs referenced by the parent are in the same VRF. It cannot be used to establish connectivity between tenant networks that have different VRFs. For instance, a contract between a provider and consumer EPG deployed in the same common tenant is not possible. This is because the contract must be visible to both tenants, which requires that the contract object be in the common tenant.
