location
Syntax location location
no location
Context config>system
Description This command creates a text string that identifies the system location for the device.
Only one location can be configured. If multiple locations are configured, the last one entered
overwrites the previous entry.
The no form of the command reverts to the default value.
Default n/a — no system location is configured
Parameters location — the location as a character string. Allowed values are any string up to 80
characters long composed of printable, 7-bit ASCII characters. If the string contains
spaces, the entire string must be enclosed within double quotes.
lsr-load-balancing
Syntax lsr-load-balancing hashing-algorithm [bottom-of-stack hashing-treatment] [use-ingress-
port]
no lsr-load-balancing
Context config>system
Description This command configures system-wide LSR load balancing. Hashing can be enabled on the
IP header at an LSR to send labeled packets over multiple equal-cost paths in an LDP LSP
and/or over multiple links of a LAG group in all types of LSPs.
The bottom-of-stack option determines the significance of the bottom-of-stack label (VC
label) based on which label stack profile option is specified.
When LSR load balancing is enabled, the default configuration for the hashing algorithm is
label-only (lbl-only) hashing, and the default configuration for the bottom-of-stack hashing
treatment is profile-1.
The use-ingress-port option, when enabled, specifies that the ingress port will be used by
the hashing algorithm at the LSR. This option should be enabled for ingress LAG ports
because packets with the same label stack can arrive on all ports of a LAG interface. In this
case, using the ingress port in the hashing algorithm will result in better egress load
balancing, especially for pseudowires.
The option should be disabled for LDP ECMP so that the ingress port is not used by the
hashing algorithm. For ingress LDP ECMP, if the ingress port is used by the hashing
algorithm, the hash distribution could be biased, especially for pseudowires.
