Read-only ArgumentTypeDescription
error-codenumError code when L3HW driver is in a failure state.
stateenum (ok | stopping | starting | fib-failure | net-failure | switch-failure | fasttrack-failure | out-of-memory) { ok:0, stopping:1, starting:2, fib-failure:3, net-failure:4, switch-failure:5, fasttrack-failure:6, out-of-memory:0xFFFFFFF4 }Current state of the L3HW driver.
ipv4-routes-totalnumThe total number of IPv4 routes handled by the switch driver.
ipv4-routes-hwnumThe number of hardware-offloaded IPv4 routes (a.k.a. hardware routes).
ipv4-routes-cpunumThe number of IPv4 routes redirected to the CPU (a.k.a. software routes).
ipv4-shortest-hw-prefixnumShortest Hardware Prefix (SHWP) for IPv4. If the entire IPv4 routing table does not fit into the hardware memory, partial offloading is applied, where the longest prefixes are hw-offloaded while the shorter ones are redirected to the CPU. This field shows the shortest route prefix (/x) that is offloaded to the hardware memory. All prefixes shorter than this are processed by the CPU. ipv4-shortest-hw-prefix=0 means the entire IPv4 routing table is offloaded to the hardware memory.
ipv4-hostsnumThe number of hardware-offloaded IPv4 hosts (/32 routes).
ipv6-routes-totalnumThe total number of IPv6 routes handled by the switch driver.
ipv6-routes-hwnumThe number of hardware-offloaded IPv6 routes (a.k.a. hardware routes). Shown only when IPv6 hardware routing is enabled (ipv6-hw=yes).
ipv6-routes-cpunumThe number of IPv6 routes redirected to the CPU (a.k.a. software routes). Shown only when IPv6 hardware routing is enabled (ipv6-hw=yes).
ipv6-shortest-hw-prefixnumShortest Hardware Prefix (SHWP) for IPv6. If the entire IPv6 routing table does not fit into the hardware memory, partial offloading is applied, where the longest prefixes are hw-offloaded while the shorter ones are redirected to the CPU. This field shows the shortest route prefix (/x) that is offloaded to the hardware memory. All prefixes shorter than this are processed by the CPU. ipv6-shortest-hw-prefix=0 means the entire IPv6 routing table is offloaded to the hardware memory. Shown only when IPv6 hardware routing is enabled (ipv6-hw=yes).
ipv6-hostsnumThe number of hardware-offloaded IPv6 hosts (/128 routes). Shown only when IPv6 hardware routing is enabled (ipv6-hw=yes).
route-queue-size (syscap=!prestera-cpss)numThe number of routes in the queue for processing by the switch chip driver. Under normal working conditions, this field is 0, meaning that all routes are processed by the driver.
route-queue-rate (syscap=!prestera-cpss)numThe rate at which routes are added to the queue for processing by the switch driver (growth rate of route-queue-size routes per second).
route-process-rate (syscap=!prestera-cpss)numThe rate at which previously queued routes are processed by the switch driver (shrink rate of route-queue-size routes per second)..
nexthop-capnumThe nexthop capacity.
nexthop-usagenumThe number of currently used nexthops.
vxlan-mtu-packet-drop (syscap=prestera-bc2)numThe number of dropped VXLAN packets due to exceeded interface MTU settings.
fasttrack-ipv4-conns (syscap=prestera-bc2)numThe number of hardware-offloaded FastTrack connections. Parammeter appear only when hardware offloading of FastTrack connections is enabled.
fasttrack-queue-size (syscap=prestera-bc2)numThe number of FastTrack connections in the queue for processing by the switch chip driver.
fasttrack-queue-rate (syscap=prestera-bc2)numThe rate at which FastTrack connections are added to the queue for processing by the switch driver (growth rate of fasttrack-queue-size connections per second).
fasttrack-process-rate (syscap=prestera-bc2)numThe rate at which previously queued FastTrack connections are processed by the switch driver (shrink rate of fasttrack-queue-size connections per second).
fasttrack-hw-min-speed (syscap=prestera-bc2)numWhen the hardware memory for storing FastTrack is full, this field shows the minimum speed (in bytes per second) of a hw-offloaded FastTrack connection. Parammeter appear only when hardware offloading of FastTrack connections is enabled.
fasttrack-hw-offloaded (syscap=prestera-bc2)numThe number of FastTrack connections offloaded to the hardware. The counter resets every second.
fasttrack-hw-unloaded (syscap=prestera-bc2)numThe number of FastTrack connections unloaded from the hardware (redirected to software routing). The counter resets every second.
lpm-cap (syscap=!prestera-ac3)numThe size of the LPM hardware table (LPM = Longest Prefix Match). LPM stores route indexes for hardware routing. Not every switch chip model uses LPM. Others use TCAM.
lpm-usage (syscap=!prestera-ac3)numThe number of used LPM blocks.
lpm-bank-cap (syscap=!prestera-ac3)numLPM memory is organized in banks. This value shows the size of a single bank (in LPM blocks). The bank size depends on the switch chip model. lpm-cap / lpm-bank-cap = the number of banks.
lpm-bank-usage (syscap=!prestera-ac3)multi { array-id, lpm-bank: num }Per-bank LPM usage (in LPM blocks).
pbr-cap (syscap=prestera-bc2)numThe size of the Policy-Based Routing (PBR) hardware table. PBR is used for NAT offloading of FastTrack connections.
pbr-usage (syscap=prestera-bc2)numThe number of used PBR entries.
pbr-lpm-bank (syscap=prestera-bc2)numPBR shares LPM memory banks with routing tables. This value shows the LPM bank index shared with PBR (0 = the first bank).
nat-usage (syscap=prestera-bc2)numThe number of used NAT hardware entries (for FastTrack connections).
