configure ports rate-limit egress
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
ExtremeWare XOS 11.5 Command Reference Guide
877
configure ports rate-limit egress
configure ports <port_list> rate-limit egress [no-limit | <cir-rate> [Kbps
| Mbps | Gbps] {max-burst-size <burst-size> [Kb | Mb]}]
Description
Configures an egress traffic rate limit for a port or groups of ports.
Syntax Description
Default
No-limit.
Usage Guidelines
Port speed limits the egress traffic, as follows:
●
1 Gbps port—64 Kbps increments
●
10 Gbps port—1 Mbps increments
If the specified egress limit (
cir-rate
) is not a multiple of 64 Kbps for a 1 Gbps port or 1 Mbps for a
10 Gbps port, the specified value is rounded down to the nearest appropriate multiple based on the port
type.
Use the
no-limit
parameter to:
●
Unconfigure egress rate limiting on the port(s)
●
Reconfigure existing egress rate limiting on the port(s)
The max-burst-size parameter is the amount of traffic above the value in the
cir-rate
parameter that is
allowed to burst from the port(s) for a short duration.
Example
The following command configures egress rate-limiting on slot 3 port 1 on a modular switch for 3 Mbps
and a maximum burst size or 5 M bits:
configure port 3:1 rate-limit egress 3 Mbps max-burst-size 5 Mb
port_list
Specifies one or more ports or slots and ports.
no-limit
Specifies traffic be transmitted without limit; use to reconfigure or unconfigure previous
rate-limiting parameters.
cir-rate
Specifies the desired rate limit in Kbps, Mbps, or Gbps.
max-burst-size
Specifies amount of traffic above the cir-rate that is allowed to burst (for a short duration)
from the port in K bits (Kb) or M bits (Mb).
