roce
roce [< lossy | semi-lossless | lossless >] [no] roce Configures the switch to RoCE mode. The no form of the command disables RoCE mode. | ||
Syntax Description | Lossless | Full PFC support (this is the default when no parameter is chosen). |
| Semi-lossless | Micro-burst absorption (pause rx compliant, no pause propagation). | |
Lossy | Congestion control based on ECN marking only. No PFC support. | |
Default | N/A | |
Configuration Mode | config | |
History | 3.8.2000 | |
Example | switch (config) # roce <mode> switch (config) # no roce switch (config) # show roce RoCE mode: N/A switch (config) # | |
