Mixed speed port channel

Description Starting with the 4.26.1F release, EOS supports active mixed speed members in a port-channel, allowing different speed ports to aggregate. Mixed speed port-channels can be enabled using a CLI configuration command. By default the feature is disabled. The mixed speed port-channel feature introduces the concept of ”weight” associated with a port-channel member. The weight of a member port is directly proportional to the other members’ speeds and it determines the ratio of packets sent over that member port if it becomes active. For same speed port-channels, all members have a weight of 1. The ”weight” value has been added...

Maximum port channel ID increase

Description Previously, the maximum valid port channel ID was equal to the maximum number of port channels configurable on the system, 2000, and this feature increases the maximum ID to 999,999 while maintaining the same limit of 2000 port channels on the system. Platform compatibility DCS-7010 DCS-7020 DCS-7050 DCS-7060 DCS-7250 DCS-7260 DCS-7280 DCS-7500 DCS-7516 DCS-7800 DCS-7808 Configuration This feature does not involve any specific configuration procedure, but it does include visible changes to port channel configuration commands. In the following examples, suppose port channels 1-2000 have already been configured, so creating Port-Channel2001 would exceed the config limit. switch(config)#interface create port-channel...

Support to configure system MAC address

Description Some users need to configure the source MAC on routed ports, in some cases.To achieve this,a new CLI configuration command has been added to allow the user to override the system MAC. All L3 interfaces use the same system MAC. This command is available for fixed systems only configured system MAC will be set after reboot. Platform compatibility All fixed systems support the system MAC address CLI command. DCS-7010 DCS-7050 DCS-7060 DCS-7150 DCS-7160 DCS-7250 DCS-7260 DCS-7280 Configuration The following global configuration command can be used to configure a system MAC address: switch(config)# system mac-address 001c.7374.0744 ! Change will take...

Port-security – preserve MACs on link flap/reload

General points Persistent port security is a new feature that is applicable to the port security protect mode (https://eos.arista.com/eos-4-15-3f/portsec/). Persistent port-security is a platform independent feature. Persistent port-security ensures that port-security MAC cache and any restriction applied are preserved across link flap and system reload. No new configuration  or show commands are added for this feature. Please refer to https://eos.arista.com/eos-4-15-3f/portsec/ for existing commands. Clear port-security MAC addresses learned/configured on the interface are persistent, i.e. the port security MAC cache will not be updated when forwarding database entries are changed (e.g. an address aged out or is deleted from configuration). To clean up stale forwarding...
