Limits

This chapter summarizes the supported limits in ExtremeXOS 21.1.

Supported Limits summarizes tested metrics for a variety of features, as measured in a per-system basis unless otherwise noted. These limits may change, but represent the current status. The contents of this table supersede any values mentioned in the ExtremeXOS books.

The scaling and performance information shown in Supported Limits is provided for the purpose of assisting with network design. It is recommended that network architects and administrators design and manage networks with an appropriate level of network scaling “head room.” The scaling and performance figures provided have been verified using specific network topologies using limited switch configurations. There is no guarantee that the scaling and performance figures shown are applicable to all network topologies and switch configurations and are provided as a realistic estimation only. If you experience scaling and performance characteristics that you feel are sufficiently below what has been documented, contact Extreme Networks technical support for additional assistance.

The route limits shown in Supported Limits for IPv4 and IPv6 routing protocols are software limits only. The actual hardware limits may be higher or lower than the software limits, based on platform. The hardware limits for specific platforms are specified as "IPv4/IPv6 routes (LPM entries in hardware)" in the following table.

It is not advised to have greater than 25,000 total IP routes from all routing protocols. Adverse effects can occur with routing tables larger than this, especially when a single network event or CLI command affects a significant number of routes. For example, just after such a network event, the added system load will cause a save configuration command to time out.

a The table shows the total available.
b Limit depends on setting configured for "configure forwarding external-tables".
c When there are BFD sessions with minimal timer, sessions with default timer should not be used.
d Based on in “none more-l2” mode.
e Based on forwarding internal table configuration "more l2”.
f Effective capacity varies based on actual MAC addresses and VLAN IDs used and hash algorithm selected.
g Based on “l2-only mode”.
h Based on forwarding internal table configuration "more l3-and-ipmc”.
i Based on forwarding external table configuration "l3-only ipv4".
j The limit depends on setting configured with configure iproute reserved-entries.
k Based on forwarding external table configuration "l3-only ipv4”.
l Based on forwarding external table configuration "l3-only ipv6”.
m The IPv4 and IPv6 multicast entries share the same hardware tables, so the effective number of IPv6 multicast entries depends on the number of IPv4 multicast entries present and vice-versa.
n If IGMP and MLD are simultaneously configured on the switch, the number of effective subscribers supported would be appropriately lessened.
o Sum total of all PBR next hops on all flow redirects should not exceed 4,096.
p The number of XNV authentications supported based on system ACL limitations.
