Description
Power over Ethernet (PoE)
The Cisco 887VA Integrated Services Router (CISCO887VA-SEC-K9) has support for Power over Ethernet (PoE) on some of its Ethernet ports. PoE allows the router to receive power over the same cable that is used to transmit data, eliminating the need for a separate power cable. This can be useful for powering devices such as IP phones and wireless access points that are located in areas where power outlets may not be readily available.
The 887VA-SEC-K9 model has 4 10/100/1000 Ethernet ports and 1 10/100/1000 Ethernet ports with PoE. The PoE feature allows the router to supply power to devices that are connected to the PoE-enabled Ethernet ports, as long as the devices are IEEE 802.3af compliant. It can support a maximum of 15.4W per port to power devices.
It is important to note that the PoE feature is only available on the specific model CISCO887VA-SEC-K9, not all Cisco 887VA models have the PoE feature. And also the total PoE power budget is limited to 72W and make sure the power budget of your devices is within this limit.
Network Address Translation (NAT)
Network Address Translation (NAT) is a feature that allows multiple devices on a private network to share a single public IP address. This is commonly used to conserve IP addresses and to allow devices on a private network to access the internet.
The Cisco 887VA Integrated Services Router supports NAT, which allows the router to translate the private IP addresses of devices on a local network to a single public IP address when accessing the internet. This enables multiple devices to share a single IP address while still being able to access the internet.
There are two types of NAT on Cisco routers:
- Static NAT: maps a single private IP address to a single public IP address. This is typically used to provide internet access to a specific device, such as a web server.
- Dynamic NAT: maps a range of private IP addresses to a range of public IP addresses. This is typically used to provide internet access to a group of devices, such as a group of computers on a local network.
You can configure NAT on the Cisco 887VA router by using the Cisco IOS command-line interface (CLI). The specific commands and configuration steps will depend on the type of NAT you want to use and the specific network requirements. It is recommended to consult Cisco documentation for more details on how to configure NAT on the Cisco 887VA Router.
Intrusion Prevention System (IPS)
The Cisco 887VA Integrated Services Router (ISR) supports an Intrusion Prevention System (IPS) feature that can be used to detect and prevent known attacks on the network. The IPS feature uses a database of attack signatures to identify and block potentially malicious traffic. The feature is implemented via the router’s IOS software and can be configured through the command-line interface (CLI) or through a web-based graphical user interface (GUI).
The IPS feature on the Cisco 887VA ISR can be used in two different modes:
- Inline mode: In this mode, the IPS feature will actively inspect and block traffic that matches an attack signature.
- Promiscuous mode: In this mode, the IPS feature will passively monitor traffic and generate alerts for traffic that matches an attack signature, but it will not block the traffic.
Additionally, the Cisco 887VA ISR also support advanced features such as:
- Global Correlation Engine (GCE)
- Advanced Malware Protection (AMP)
- Reputation-based security
- Advanced Malware Protection (AMP)
It’s important to note that an IPS alone is not enough to provide comprehensive network security. It should be used in conjunction with other security measures such as firewalls, VPNs, and access control lists (ACLs) to provide a layered defense against attacks.
