Admin > Forwarding Database

Switches store the addresses for all known devices in a forwarding database.. This information is used to forward traffic directly between the inbound and outbound ports.. All the addresses learned by monitoring traffic are stored in the dynamic address table.. You can also manually configure static addresses that are bound to a specific port..

Address Aging

Sets the aging time for entries in the forwarding database.. The aging time is used to age out dynamically learned forwarding information..

Aging Status  When enabled, dynamic MAC addresses are discarded after the Aging Interval has expired..

Aging Interval (secs) (10-1000000)  This is the amount of time after which dynamic address table entries are discarded..

Set the Aging Interval by entering the number of seconds into the text field provided..

Click Save Settings to save the changes..

Static Address Setting

A static address can be assigned to a specific interface on the Switch.. Static addresses are bound to the assigned interface and will not be moved.. When a static address is seen on another interface, the address will be ignored and will not be written to the address table..

Static Address Counts  The number of manually configured addresses.. The Switch allows 1000 Static Address Counts..

Interface  Port or LAG associated with the device assigned a static address..

MAC Address (XX-XX-XX-XX-XX-XX)  Physical address of a device mapped to this interface..

VLAN  ID of a configured VLAN (1-4094)..

Specify the interface, the static MAC address, and VLAN, then click Add.. The current static addresses on the Switch are all displayed in a list.. To delete a static MAC address from the forwarding database, select the entry in the displayed list, then click Remove..

Dynamic Address Query

The Switch’s dynamic address table contains the MAC addresses learned by monitoring the source address for traffic entering the Switch.. When the destination address for inbound traffic is found in the database, the packets intended for that address are forwarded directly to the associated port.. Otherwise, the traffic is flooded to all ports..

You can query the forwarding database to find specific dynamicMACaddresses, orviewMAC addressesassociated with a specific interface or VLAN..

Dynamic Address Counts  The number of addresses dynamically learned on the Switch..

Interface  Select to display MAC addresses for a specific port or LAG..

MAC Address  Select to display details for a specific MAC address..

VLAN  Select to display MAC addresses for a specific configured VLAN (1-4094)..

Address Table Sort Key  Sorts the information displayed based on MAC address, VLAN, or interface (port or LAG)..

Specify the search type (that is, check the Interface, MAC Address, or VLAN checkbox), select the method of sorting the displayed addresses, and then click Query.. The dynamic addresses that conform to the search criteria are displayed.. To delete a MAC address from the forwarding database, select the entry in the displayed list, then click Remove..

SRW248G4P specifications

Cisco Systems SRW248G4P is a high-performance Layer 2 switch designed specifically for small to medium-sized businesses that require robust networking solutions. This switch supports Power over Ethernet (PoE), providing a highly flexible option for powering devices such as IP phones, wireless access points, and surveillance cameras.

One of the standout features of the SRW248G4P is its 48 10/100 Ethernet ports, which ensure ample connectivity for various networked devices. Additionally, it offers four Gigabit Ethernet uplink ports, allowing for seamless integration with existing network infrastructure and facilitating high-speed data transfer. The combination of these ports enables businesses to expand their network capabilities as needed without the immediate requirement for added devices.

The SRW248G4P comes equipped with advanced Layer 2 switching capabilities, including VLAN support, which enables the segmentation of network traffic for improved performance and security. It also supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), which help prevent network loops and ensure redundancy. With features like Link Aggregation Control Protocol (LACP), multiple physical connections can be combined into a single logical link, enhancing bandwidth and providing failover capabilities.

Another critical attribute of the Cisco SRW248G4P is its user-friendly management interface. The switch can be managed through a web-based interface, allowing IT administrators to configure settings, monitor performance, and troubleshoot issues with ease. Additionally, it supports SNMP (Simple Network Management Protocol) for integration with network management systems, further simplifying monitoring tasks.

Power over Ethernet functionality is a significant advantage of the SRW248G4P, providing up to 15.4 watts per port. This capability simplifies installation and reduces the clutter of power cords and outlets. Organizations can deploy PoE-enabled devices in locations that lack power sources, thus enhancing overall flexibility in network design.
