Configuration Commands
This section includes TWAMP configuration commands.
test-session (TWAMP Sender)
Command Objective:
This command configures the TWAMP sender test-session.
Syntax:
test-session {[name <string(43)>}] [{admin-state { "disable" | "enable" } }] [{sender-udp-port <integer(1-65535)>} [{reflector-ip {<ipv4_addr>|<ip6_addr>}}] [{reflector-udp-port <integer(1-65535)>}] [{dscp <integer(0-63)>}] [{size-select {“padding-length“ | “payload-size“}}] [{padding-length <integer(27-1458)>}] [{payload-size <integer(41-1472)>}] [{padding-pattern “all-zero” | “random”}] [{periodic-interval {"10" | "20" | "33" | "50"| "100" | "1000"}}] [{measurement-interval {"60" | "300" | "600" | "900"| "3600"}}] [{metric-profile sla}]
Parameter Description:
- name - TWAMP Session-Sender name. It should be unique.
- admin-state - Used to enable or disable operation of a TWAMP Session-Sender. Default value is enable.
Note: This is the only parameter that can be modified after creation. - reflector-ip - The reflector IP address (format IPv4 or IPv6)
- sender-udp-port - UDP sender port number. Default value is 862.
- reflector-udp-port - UDP sender port number. Default value is 862.
- dscp - The DSCP value for this test session.
- size-select - Define the length of the TWAMP-Test Packet by specifying the number of padding bytes to append or by specifying the UDP Payload size. Default value is “padding-length.
- padding-length - The number of padding bytes added to the TWAMP-Test Packet. Default value is 36.
- payload-size - The size of the TWAMP-Test Packet including any padding. Default value is 50.
- padding-pattern - Padding pattern used for frame padding. Default value is all-zero.
- periodic-interval - Time interval between transmission of two consecutive packets in millisecond. Default value is 1000 ms.
- measurement-interval - Metric aggregation period time in Telemetry module in seconds. Default value is 15 minutes.
- metric-profile - Telemetry metric profile.
Mode:
TWAMP Sender (config-twamp-sender)
Note: The TWAMP sender session is created within the context of a specific Offload Engine Switch Virtual Interface (OE-SVI) instance and therefore implicitly inherits any needed attributes.
Example:
Your Product(config)# oe-svi 1
Your Product(config-oe-svi)# oe-twamp-session-sender 1
Your Product(config-twamp-sender) # test-session name TWPL_Sender_1 admin-state enable sender-udp-port 37266 reflector-ip 1.1.1.5 padding-length 1381 measurement-interval 60
oe-twamp-session-sender
Command Objective:
This command enters the TWAMP sender test-session
The no form of the command deletes the TWAMP sender test-session.
Syntax:
oe-twamp-session-sender < integer >
no oe-twamp-session-sender < integer >
Parameter Description:
- Id - Sender session ID
Mode:
Offload Engine Switch Virtual Interface (config-oe-svi)
Example:
Your Product(config-oe-svi)# oe-twamp-session-sender
test-session (TWAMP Reflector)
Command Objective:
This command configures a TWAMP session reflector test-session.
By default the TWAMP reflector is started as soon as it is configured if status is enable.
Syntax:
test-session {[name <string(43)>} ] [{admin-state { "disable" | "enable" } }] [{sender-ip {<ipv4_addr>|<ip6_addr>}}] [{sender-udp-port <integer(1-65535)>}] [{reflector-udp-port <integer(1-65535)>}]
Parameter Description:
- name - Session name
- admin-state - Used to enable or disable operation of a TWAMP Session-Reflector. Default value is enable.
Note: This is the only parameter that can be modified after creation. - sender-ip - IP address format IPv4 or IPv6 of the Sender.
- reflector-udp-port - UDP local port number. Default value is 862.
- sender-udp-port - UDP remote port number. Default value is 862.
Mode:
TWAMP Reflector (config-twamp-reflector)
Notes: The TWAMP sender session is created within the context of a specific Offload Engine Switch Virtual Interface (OE-SVI) instance and therefore implicitly inherits any needed attributes.
Admin State:
enable: TWAMP Session is enabled
disable: TWAMP Session is disabled
Operational Status:
disabled: Admin State is not enabled
up: VLAN state is up AND Ethernet link state is up AND the ARP cache status is valid
down: VLAN state is down OR Ethernet link state is down OR ARP cache status is not valid
Example:
Your Product(config)# oe-svi 1
Your Product(config-oe-svi)# oe-twamp-session-reflector 1
Your Product(config-twamp-reflector) # test-session name TWPL_Reflector_1 sender-ip 1.1.1.1 sender-udp-port 28051
oe-twamp-session-reflector
Command Objective:
This command enters the TWAMP reflector test-session
The no form of the command deletes a TWAMP reflector test-session.
Syntax:
oe-twamp-session-reflector < integer(1-65535) >
no oe-twamp-session-reflector < integer(1-65535) >
Parameter Description:
- Id - Session ID
Mode:
Offload Engine Switch Virtual Interface (config-oe-svi)
Example:
Your Product(config-oe-svi)# oe-twamp-session-sender
