Cloud Router Switch configuration examples

Abbreviations and Explanations

CVID - Customer VLAN id: inner VLAN tag id of the IEEE 802.1ad frame

SVID - Service VLAN id: outer VLAN tag id of the IEEE 802.1ad frame

IVL - Independent VLAN learning - learning/lookup is based on both MAC addresses and VLAN IDs.

SVL - Shared VLAN learning - learning/lookup is based on MAC addresses - not on VLAN IDs.

TPID - Tag Protocol Identifier

PCP - Priority Code Point: a 3-bit field which refers to the IEEE 802.1p priority

DEI - Drop Eligible Indicator

DSCP - Differentiated services Code Point

Drop precedence - internal CRS switch QoS attribute used for packet enqueuing or dropping.

Port Switching

Similarly to other RouterBoards, port switching on CRS allows wire-speed traffic forwarding among a group of ports, like the ports were a regular Ethernet switch. This feature is configurable by setting a "master-port" property to one or more ports in /interface ethernet menu. The "master-port" will be the port through which the RouterOS will communicate to all ports in the group. Interfaces which have the "master-port" specified become isolated - no traffic can be received and no traffic can be sent out directly from RouterOS.

Here is a general diagram of RouterBoard with a five port switch chip:

Switch-png.png

A packet that is received by one of the ports always passes through the switch logic first. Switch logic decides to which ports the packet should be going to. Passing packet "up" or giving it to RouterOS is also called sending it to switch chip's “CPU” port. It means at that point switch forwards the packet to CPU port the packet starts to get processed by RouterOS as incoming packet of the “master-port”. If the packet does not have to go to “CPU” port, it is handled entirely by switch logic, does not require any CPU resources and happens at wire-speed.

Additionally, CRS series switches support multiple “master-port” configurations and have no port selection limitations for a port group which makes possible many various switched port combinations with all CRS switch interfaces. But no port can be in more than one switch group.

For example, consider a CRS125 switch with 24 Ethernet interfaces and 1 SFP interface:

And there are configured 3 switch groups: 1) ether2, ether3, ether4, ether5, ether6; 2) ether13, ether14, ether15, ether16, ether17, ether18, ether19, ether20; 3) ether21, ether22, ether23, ether24, sfp1.

Ports ether1, ether7-ether12 are not switched in this example, they remain as independent router ports.

Now ether2 is the “master-port” of the group 1, ether13 – of the group 2 and ether21 – of the group 3.

Note: Previously a link was detected only on interfaces with a physical connection, but now since the ether2, ether13 and ether21 have connection to CPU, the running flag is propagated to them, as well.

CRS Port Switching Example

In essence this configuration is the same as if you had a RouterBoard with 10 Ethernet interfaces and 3 switches:

Alt text
CRS Port Switching Logic
Icon-note.png

Note: Dynamic reserved VLAN entries (VLAN4091; VLAN4090; VLAN4089; etc.) are created in CRS switch when switched port groups are added by setting new master-ports. These VLANs are necessary for internal operation and have lower precedence than user configured VLANs.


Icon-note.png

Note: Multiple master-port configuration is designed as fast and simple port isolation solution, but it limits a part of VLAN functionality supported by CRS switch-chip. For advanced configurations use one master-port within CRS switch chip for all ports, configure VLANs and isolate port groups with port isolation profile configuration.

Port Isolation/Leakage

Sub-menu: /interface ethernet switch port-isolation


Sub-menu: /interface ethernet switch port-leakage


The CRS switches support flexible multi-level isolation features, which can be used for user access control, traffic engineering and advanced security and network management. The isolation features provide an organized fabric structure allowing user to easily program and control the access by port, MAC address, VLAN, protocol, flow and frame type. The following isolation and leakage features are supported:

  • Port-level isolation
  • MAC-level isolation
  • VLAN-level isolation
  • Protocol-level isolation
  • Flow-level isolation
  • Free combination of the above

Port-level isolation supports different control schemes on source port and destination port. Each entry can be programmed with access control for either source port or destination port.

  • When the entry is programmed with source port access control, the entry is

applied to the ingress packets.

  • When the entry is programmed with destination port access control, the entry

is applied to the egress packets.

Port leakage allows bypassing egress VLAN filtering on the port. Leaky port is allowed to access other ports for various applications such as security, network control and management. Note: When both isolation and leakage is applied to the same port, the port is isolated.

  • drop - Packets are dropped if they match the ACL conditions.
  • forward - Packets are forwarded if they match the ACL conditions.
  • redirect-to-cpu - Packets are redirected to CPU if they match the ACL conditions.
  • send-to-new-dst-ports - Packets are send to new destination ports if they match the ACL conditions.
new-dst-ports (ports,trunks) If action is "send-to-new-dst-ports", then this property sets which ports/trunks is the new destination.
mirror-to (mirror0 | mirror1) Mirroring destination for ACL packets.
policer (policer) Applied ACL Policer for ACL packets.
src-mac-learn (yes | no) Whether to learn source MAC of the matched ACL packets. Valid only in ingress policy table.
new-service-vid (0..4095) New service VLAN id for ACL packets.
new-service-pcp (0..7) New service PCP for ACL packets.
new-service-dei (0..1) New service DEI for ACL packets.
new-customer-vid (0..4095) New customer VLAN id for ACL packets. If set to 4095, then traffic is dropped.
new-customer-pcp (0..7) New customer PCP for ACL packets.
new-customer-dei (0..1) New customer DEI for ACL packets.
new-dscp (0..63) New DSCP for ACL packets.
new-priority (0..15) New internal priority for ACL packets.
new-drop-precedence (drop | green | red | yellow) New internal drop precedence for ACL packets.
new-registered-state (yes | no) Whether to modify packet status. YES sets packet status to registered, NO - unregistered. Valid only in ingress policy table.
new-flow-id (0..63)


Filter bypassing part for ACL packets.

Property Description
attack-filter-bypass (yes | no; Default: no)
ingress-vlan-filter-bypass (yes | no; Default: no) Allows to bypass ingress VLAN filtering in VLAN table for matching packets. Applies only to ingress policy table.
egress-vlan-filter-bypass (yes | no; Default: no) Allows to bypass egress VLAN filtering in VLAN table for matching packets. Applies only to ingress policy table.
isolation-filter-bypass (yes | no; Default: no) Allows to bypass Isolation table for matching packets. Applies only to ingress policy table.
egress-vlan-translate-bypass (yes | no; Default: no) Allows to bypass egress VLAN translation table for matching packets.


ACL Policer

Sub-menu: /interface ethernet switch acl policer


Property Description
name (string; Default: policerX) Name of the Policer used in ACL.
yellow-rate (integer) Maximum data rate limit for packets with yellow drop precedence.
yellow-burst (integer; Default: 0) Maximum data rate which can be transmitted while the burst is allowed for packets with yellow drop precedence.
red-rate (integer); Default: 0) Maximum data rate limit for packets with red drop precedence.
red-burst (integer; Default: 0) Maximum data rate which can be transmitted while the burst is allowed for packets with red drop precedence.
meter-unit (bit | packet; Default: bit) Measuring units for ACL traffic rate.
meter-len (layer-1 | layer-2 | layer-3; Default: layer-1) Packet classification which sets the packet byte length for metering.
  • layer-1 - includes entire layer-2 frame + FCS + inter-packet gap + preamble.
  • layer-2 - includes layer-2 frame + FCS.
  • layer-3 - includes only layer-3 + ethernet padding without layer-2 header and FCS.
color-awareness (yes | no; Default: no) YES makes policer to take into account pre-colored drop precedence, NO - ignores drop precedence.
bucket-coupling (yes | no; Default: no)
yellow-action (drop | forward | remark; Default: drop) Performed action for exceeded traffic with yellow drop precedence.
new-dei-for-yellow (0..1 | remap) New DEI for yellow drop precedence packets.
