HTTP and HTTPS on Cisco IOS Routers
HTTP and HTTPS on Cisco IOS Routers
Security Manager enables you to configure HTTP and HTTP over Secure Socket Layer (known as HTTP
over SSL or HTTPS) server functionality on Cisco IOS routers. This feature provides SSL version 3.0
support for the HTTP 1.1 server.
A secure HTTP connection means that data sent to and received from an HTTP server are encrypted
before being sent out over the internet. HTTP with SSL encryption provides a secure connection to allow
such functions as configuring a router from a web browser.
In addition to providing access to the device via the Cisco web browser user interface, HTTP and HTTPS
are used by device management applications, such as the Cisco Router and Security Device Manager
(SDM), to communicate with the device.

CPU Process Utilization The thresholds for CPU process utilization that trigger notifications:
•Enable CPU Process Utilization—When selected, CPU process
utilization thresholds are enabled. When deselected, these
thresholds are disabled and do not trigger notifications. This is the
default.
•Maximum Process Utilization Resources—The percentage of CPU
resources that, when usage exceeds this level for the defined
interval, triggers a notification.
•Maximum Process Utilization Violation Duration—The violation
interval that triggers a maximum CPU threshold notification. Valid
values range from 5 to 86400 seconds (24 hours).
•Minimum Process Utilization Resources—The percentage of CPU
resources that, when usage falls below this level for the defined
interval, triggers a notification.
•Minimum Process Utilization Violation Duration—The violation
interval that triggers a minimum CPU threshold notification. Valid
values range from 5 to 86400 seconds (24 hours).
Extended CPU History Size The size of the history to collect for the extended CPU load, in
increments of 5 seconds. Valid values range from 2 to 720. The default
is 12, which is equivalent to a 1-minute history.
Enable Automatic CPU Hog
Profiling
When selected, automatic CPU Hog profiling is enabled. This is the
default.
When deselected, automatic CPU Hog profiling is disabled.
This feature predicts when a process could hog the CPU and begins
profiling that process.
Note To view the CPU Hog profile data, use the show processes cpu
autoprofile hog command in the CLI.
