Purpose
The clock manager adjusts the ERSPAN timers based
Note
on the granularity setting. If you configure IEEE 1588,
the clock manager synchronizes the ERSPAN timers
across switches. Otherwise, the clock manager
synchronizes the ERSPAN timer with the master timer
in the switch.
Note 1588 granularity mode is not supported in Cisco
NX-OS Release 6.1 and is rejected if selected.
M2 Series modules support 100 ms, 100 ns, and ns
Note
granularity. F2 series and F2e Series modules support
only 100 ms and 100 ns granularity.
Note This command can be applied only in the default
VDC.
Clears the configuration of the specified ERSPAN session. The
new session configuration is added to the existing session
configuration.
Configures an ERSPAN Type II source session. By default the
session is bidirectional. The optional keywords are as follows:
• rx—Specifies an ingress extended ERSPAN source
session.
• tx—Specifies an egress extended ERSPAN source session.
• shut—Specifies a shut state for the selected session.
(Optional)
Configures the ERSPAN source session as an extended
bidirectional session.
You cannot use this command on a unidirectional
Note
ERSPAN source session.
(Optional)
Changes the ERSPAN source session from Type II to Type III.
Note You can use the no form of this command to change
an ERSPAN source session from Type III to Type II.
(Optional)
Configures a description for the session. By default, no
description is defined. The description can be up to 32
alphanumeric characters.
Configures the filter for the ERSPAN session. To remove the
filter from the session, enter the no form of the command. The
optional keywords are as follows:
• access-group—Specifies a filter based on an access
control group.
• vlan—Specifies a filter based on a VLAN range.
