To configure the global hold-time period of a speaker network device in a Cisco TrustSec Security Group
Tag (SGT) Exchange Protocol version 4 (SXPv4) network, use the cts sxp speaker hold-time command in
global configuration mode. To remove the hold time from the speaker device, use the no form of this command.

Usage Guidelines
The Security Group Tag Exchange Protocol (SXP) uses a TCP-based, keepalive mechanism to determine if
a connection is live. SXPv4 adds an optional negotiated keepalive mechanism, the hold-time period, in order
to provide more predictable and timely detection of connection loss.
Hold time can be configured globally on a network device. This global configuration will apply the configuration
to all SXP connections configured on the device.
You may configure a hold-time period locally on a speaker device or a default of 120 seconds is used. This
is the shortest period of time a speaker is willing to send keepalive messages for keeping the connection active.
Any shorter hold-time period would require a faster keepalive rate than the rate the speaker is ready to support.
A value of 0xFFFF indicates that the keepalive mechanism is not used.
The hold-time negotiation between the speaker device and the listener device succeeds when the speaker's
minimum acceptable hold time falls below or within the desirable hold-time range of the listener. (Use the
cts sxp listener hold-time command to configure the hold time of the listener device.) If one end turns off
the keepalive mechanism, the other end should also turn it off to make the negotiation successful.
The negotiation fails when the speaker's minimum acceptable hold-time is greater than the upper bound of
the listener's hold-time range.
The selected hold-time period of a successful negotiation is the maximum of the speaker's minimum acceptable
hold time and the lower bound of the listener's hold-time range.
The speaker calculates the keepalive time to one-third of the selected hold time by default, unless a different
keepalive time is locally configured.
Minimum allowed hold time in seconds. The range is from 1 to 65534.
