Router# show env table

Product Overview

The show environment table command displays the temperature and voltage thresholds for each of the three RSP2 temperature sensors, for each monitored status level: low critical, low warning, high warning, and high critical, which are the same as those listed in Tables 2 and 3. The slots in which the RSP2 can be installed are indicated in parentheses (6 and 7). Also listed are the shutdown thresholds for the processor boards and power supplies. Following is sample output of the show env table command:

Sample Point		LowCritical	LowWarning	HighWarning	HighCritical
RSP(6) Inlet				44C/111F	50C/122F
RSP(6) Hotpoint				54C/129F	60C/140F
RSP(6) Exhaust
RSP(7) Inlet				44C/111F	50C/122F
RSP(7) Hotpoint				54C/129F	60C/140F
RSP(7) Exhaust
+12	Voltage	10.76	11.37	12.64	13.24
+5 Voltage		4.49	4.74	5.25	5.52
-12	Voltage	-10.15	-10.76	-13.25	-13.86
+24	Voltage	19.06	21.51	26.51	28.87
Shutdown boards		at	101C/213F
Shutdown power supplies at			101C/213F

Note Temperature ranges and values are subject to change.

The show environment all command displays an extended report that includes the arbiter type, backplane type, power supply type (AC or DC), wattage and status, the number and type of intermittent power failures (if any) since the system was last powered on, and the currently measured values at the RSP2 temperature sensors and the DC-input lines. The show environment all command also displays a report showing which slots in the Cisco 7513 are occupied (indicated by an X) and which are empty.

Note The current monitor circuits of the 7513 power supply are only accurate at high power levels. They are there to prevent over-configuration and serve no purpose at low power levels. If the system is not operating above 70% power, the measurement results are not accurate. Above 70%, the measurements have the degree of accuracy needed to prevent the insertion of too many line cards into the system.

Active fault conditions are indicated when the blower or power supply has failed or is not present (as “Blower #3” indicates in the following example). The system expects to see three blowers or fans in the Cisco 7513: the main system blower, and one fan in each power supply. The system blower is designated #1, the power supply fan in power bay A is #2, and the power supply fan in power bay B is #3. The active fault condition in the following example shows that there is no power supply installed in power bay B because the display indicates that power supply #2 (in power bay B) is removed. System blower speed is displayed as a percentage of maximum.

There are four active trip points: restart OK, temperature warning, board shutdown, and power supply shutdown. (There are no active trip points shown in the following example.) The soft shutdowns refer to the number of times the system will reset itself before it executes a complete chassis (or hard) shutdown.

The current temperature measurements at the three RSP2 sensors are displayed as inlet, hotpoint, and exhaust. The shutdown temperature source is the hotpoint sensor, which is located toward the center of the RSP2. System voltage measurements are also displayed, followed by the system current measurements and power supply wattage calculation. Following is sample output of the show env all command:

This design allows for a mix-and-match approach to network interfaces, meaning that organizations can customize their routing capabilities according to specific needs. The router supports a variety of interface cards, including Ethernet, ATM, and POS (Packet over SONET) options, enabling seamless integration into different network topologies.

The 7513 is powered by Cisco’s innovative IOS (Internetwork Operating System), which is renowned for its reliability and feature-rich capabilities. This OS supports advanced routing protocols, including BGP, OSPF, and EIGRP, ensuring efficient data handling and routing decisions across complex and geographically dispersed networks. Additionally, the router accommodates Quality of Service (QoS) features that prioritize network traffic to guarantee optimal performance for critical applications.

In terms of performance, the Cisco 7513 can handle substantial data throughput, equipped with a powerful processor and sufficient memory capacity to support dynamic routing table populations and extensive functionalities. It is capable of delivering a routing capacity that meets the needs of both small enterprises and large service providers, making it a flexible choice.

Another significant characteristic of the 7513 is its support for redundancy and failover mechanisms. With options for redundant power supplies and enhanced cooling systems, the router is designed to operate continuously, ensuring high availability and minimal downtime. Furthermore, it supports Cisco’s High Availability features, such as Stateful Switchover, enhancing network reliability.

Security is an essential aspect of any modern router, and the Cisco 7513 comes equipped with various built-in security functionalities. These include access control lists (ACLs), Network Address Translation (NAT), and support for Virtual Private Networks (VPNs), which enable organizations to secure their data transmissions effectively.

In summary, the Cisco Systems 7513 is a versatile, high-capacity modular router suitable for a wide range of networking applications. Its advanced features, reliability, and scalability make it a critical component for enterprises and service providers seeking to enhance their infrastructure and meet evolving bandwidth demands. With its capacity to support diverse technologies and protocols, the 7513 remains a cornerstone in the realm of professional networking solutions.
