![]() The following reload command generates MLAG warning conditions that should be addressed before confirming the proceed with reload prompt. Wait for reload-delay to expire on the peer. Recommend delay is 300 seconds for TOR switches, 900 seconds for modular switches, and 600 seconds for Sand platform fixed configuration switches (70 series (except 7280CRSR2)). Refer to MLAG Availability through a Single Functional Peer for information on checking restartability.Ĭonfigure a reload delay value greater than or equal to the default. Wait for STP to be restartable: typically 30 seconds, up to 120 seconds for a newly started STP agent. If the MLAG is not actively used, then this warning can be ignored. Refer to the Release Notes to verify that the new version is compatible with the currently installed version.īring up the remote port-channel. Reload Warning Resolutions Reload Condition The following table displays the reload conditions and a common resolution method for each condition. All warnings should be resolved before confirming the reload request. Verifying Configuration CompatibilityĮntering an EOS reload command while MLAG is active generates warning messages if conditions that can result in packet loss during the upgrade are present. MLAG ISSU (In-Service Software Upgrade) upgrades EOS software on one MLAG peer with minimal traffic disruptions on active MLAG interfaces and without changing the network topology. Sessions can be reestablished if permitted by the resulting topology. Sessions established through one interface of a dual attached device may fail if its path is disrupted by the STP reconvergence, possibly resulting in temporarily lost connectivity. Severing the physical connection (cable) that establishes the peer-link between MLAG peers may result in a split brain state where each peer independently enters spanning tree state to prevent topology loops. In those cases where network topology requires additional time to stabilize or where a shorter delay can be tolerated, the reload-delay period can be configured using the reload-delay mlag command.
